[PEDA] Protel 99SE - Pick-and-Place in ASCII

2004-07-06 Thread Ray Mitchell
Hello,
Our assembly house is requesting the pick-and-place file in ASCII rather 
than XY.  Does Protel 99SE generate ASCII format?

Thanks,

Is there a way to flip an entire PCB layout along the Y axis, thereby

I was not clear.  I want to flip the entire PCB layout and be able to work 
on and modify it - not just view it.

This has been discussed extensively, and Mr. Wilson produced a server that 
would flip a whole PCB. I forget the status of that server, it might not 
be available.

But Mr. Mitchell spoke about producing a view. This is quite a different 
thing from actually flipping .. a layout. Protel does not have direct 
flip view capacity, though I think you can do it with the 3D viewer. 
However, CAMtastic can be used to view flipped gerbers. Gerbers can be 
generated as mirror images, or flipped, I think, in CAMtastic. You can 
then, if you wish, import gerber back in, perhaps putting it on a 
mechanical layer. I've done this to create single assembly drawings 
showing both sides of the board.

I haven't played with it, but I think the Print facilities can also 
produce flipped views

It has been suggested that there be a view command that flips the PCB 
display window. That would actually be relatively simple, it is a little 
surprising to me that it hasn't been done yet.

[PEDA] Can't see PCB Connections

2004-05-07 Thread Ray Mitchell
Hello,

I'm running Protel 99SE SP6 on Windows XP.  On a new PCB I working on none 
of the net connections show (you know, the stringy little threads between 
unconnected nets!).  I've gone into Document Options - Layers and turned 
everything on, including the Connections.  I've also made sure that the 
color for connections is different from the background color.  Is there 
some other place this might be turned off?

Thanks,

[PEDA] Auto router Can't Initialize error

2004-05-05 Thread Ray Mitchell
I'm running Protel 99SE SP6 on Windows XP.  Sometimes when I try to start 
the auto router I get a Can't Initialize error.  This most often occurs 
if I'm trying to autoroute a specific net, but I'm also now getting it when 
trying to autoroute All.  I have a bunch of manual pre-routes I don't 
want to lose, otherwise I'd just unroute the whole thing and start 
over.  Any suggestions?

[PEDA] Keepouts on Planes

2004-04-29 Thread Ray Mitchell
Hello,

I would like my various planes to be back 50mil from the edges of the PCB. 
I placed a line on the keepout layer and set my clearance constraint to 
50mils.  While this does keep the autorouter from placing anything closer 
than 50mils from the edge, when I look at the Gerbers for the various 
planes it appears that they go right up to the edge and ignore the 
keepout.  What is the correct procedure?

Thanks,

[PEDA] False DRC Clearance Constraint Error (99SE)?

Hello,

I have a clearance constraint between a trace on the keepout layer and a 
component on the top layer set to 0mil (I've also tried -1mil) but it still 
gives me a DRC error between the keepout trace and the component pad that 
sits on top of it.  This is obviously not the correct approach. Suggestions?

[PEDA] Can't add Planes 2-10

2004-04-21 Thread Ray Mitchell
Hello,

99SE: During my initial PCB layout stages I created internal planes 
1-13.  For the final product I reduced it to 3 internal planes.  To delete 
the excess planes I temporarily placed everything I could (split planes, 
etc.) on Plane 1 and deleted everything from the other planes.  I was then 
able to delete all those planes (using the Layer Stack Manager), leaving 
only plane 1.  However, when I try to add new planes the numbering always 
starts with plane 11, skipping 2-10.  When I look at the 
Design-Options-Layers dialog it says that only internal plane 1 is being 
used.  However, when I look at Tools-Preferences-Colors, only internal 
planes 11-16 are grayed out.  It sounds like some part of the application 
is retaining some memory of previously used planes.  Any ideas?

Thanks,
Ray

[PEDA] 99SE router gets into an infinite loop

2004-04-12 Thread Ray Mitchell
Hello,

I have noticed that about 20% of the time after I move a PCB component then 
try to reroute using Protel 99SE it gets in some sort of infinite loop 
where it appears to be placing then removing the same route over and 
over.  It makes me wish it had some sort of Kick in the ass button that 
would somehow force it to move on.  I end up having to stop it, move some 
component, then try again.  Is there some setting that controls this type 
of thing?

[PEDA] Good schematic/PCB development suite recommendation?

2004-04-09 Thread Ray Mitchell
Our group has used Protel for years.  I've tried to get everyone to change 
to something else for most of that time but the resistance has been fairly 
great.  It seems that the the philosophy has been that pain you know is 
preferable to the pain you don't know.  However, with the introduction of 
DXP/2004 everyone is starting to realize that a good tool is needed.  Is 
there something that is generally considered to be the best?  I realize 
that some of the tools cost significantly more but when the frustration, 
poor results, and wasted time are considered, it may not actually be that 
expensive.  One of the guys here uses PADS and really likes it.  If we make 
a change we don't want to make the same mistake we made with Protel again.

Re: [PEDA] Are fiducials necessary?

2004-04-09 Thread Ray Mitchell
That's good enough for me.  I'll use them.  My understanding is that in 
general:

1. They should be 1mm in diameter and have a clearance of at least 1mm 
around them.
2. They should go as close to each part as possible but need not have any 
specific or consistent distance from the parts.
3. They should be copper with no solder mask.
4. There should be some global fiducials.
5. Different assembly shops have differing needs/preferences.

Is this reasonable?  Thanks for your help.

Ray,
I work for a contract manufacturer specializing in small - medium production
volumes.  Fiducials are more than just handy!  The Pick  Place equipment 
uses
fiducials to identify board location and fine pitch part location.

If they're not present we have to jump through hoops to get parts placed
correctly.  As a result placement accuracy suffers which can force 
re-work.  This
means we have to charge you more!

[PEDA] Protel 99SE - Routing vias are all 20mil diameter w/28mil hole!

2004-04-09 Thread Ray Mitchell
Hello,

In my design rules I've specified that all routing vias are to be 20mil 
diameter with a 10mil hole.  However, the router makes them all 20mil 
diameter with a 28mil hole.  Nice feature!  I know it hasn't always done 
this - only sometimes.  I only have one design rule for routing via 
style.  Its scope is Board and it is enabled.  Am I holding my mouth 
right for some routes and wrong for others?

[PEDA] Creating selective keepouts

2004-04-08 Thread Ray Mitchell
I'm using Protel 99SE SP6.  I have components on the top and bottom of my 
board.  In one area of the bottom I would like the autorouter to be allowed 
to place both vias and traces as needed.  In another area of the bottom, 
however, I would like it to be able to place vias, as needed for routing on 
other layers, but I don't want it to be able to place any traces.  I've 
tried specifying NOT USED in the design rules for the bottom layer but when 
I do that it will not route anything anywhere.  Any thoughts on this?

[PEDA] The Protel 99SE router (router?)

2004-04-07 Thread Ray Mitchell
Hello,

Is anyone big defender of the Protel 99SE router (except maybe 
Protel)?  Here are some features I have noticed.  I'm sure this is this 
the tip of the iceberg.  Is DXP/2004 any better?  I wish that instead of 
producing new bad products they would spend their time fixing the bad ones 
they've already sold us.

1.  When I route my board using 4 signal layers it is unable to route 12 
signals.  When I give it 6 signal layers it is unable to route 24 
signals.  Is this backwards or what?

2.  It rips up and reroutes some locked pre-routed traces.

3.  In some cases it stops a trace about 1/16 from its destination pad 
even though there is nothing in the way, then produces a DRC error because 
of it.

4.  It sometimes brings vias from different nets up into a no-net polygon 
pour, shorting them all together, then produces a DRC error because of it.

5.  It sometimes lays a track from one net onto another, shorting them out, 
then produces a DRC error because of it.

Oh well, it still beats tape and a light table!

Thanks,

[PEDA] Need some router basics

2004-03-23 Thread Ray Mitchell
Hello,

I do PCB layouts very infrequently.  I've now got a fairly complicated 
routing job to do and I would appreciate some tips about the capabilities 
of Protel 99SE.  Hopefully someone can tell me if the following are 
possible and and give me some hints/suggestions:

1.  I have certain areas on several layers (different on each layer) that I 
don't want the autorouter to place traces in.  However, I do want it to be 
able to place vias in these areas as needed to help with trace routing on 
other layers.  Is this possible?

2.  My other option to the previous idea is to use blind vias in these 
areas.  What is the common wisdom concerning blind vias.  Are they 
considered nothing special, or do board fabricators consider them a big 
deal and they should be used only as a last resort?

3.  I have areas on several layers that I don't want the autorouter to 
place anything in but it's okay if it routes in this area on other 
layers.  I believe I've seen something in the help regarding the ability to 
do this.

4.  I have several BGAs with different pitches requiring different trace 
widths for escape paths.  Is it possible to have the autorouter use a 
narrower trace until it gets past the narrow area, then widen out?

Thanks,
Ray Mitchell

[PEDA] 99SE: 2 of every net name?

2004-03-17 Thread Ray Mitchell
I've never seen this before.  In 99SE (Win2K) I've created a schematic and 
am starting the PCB layout.  When I double-click on a pad and look at the 
net attached to it, as well as all the available nets, I noticed that there 
are two of every net.  For example, there are 2 A5 nets.  Some of the A5 
pads are connected to one of these nets while others are connected to the 
other, even though they all have the same A5 name.  My manually going 
through all the pads and selecting, for example, the first A5 of the pair I 
can get all A5 pads to connect together, etc.  Any ideas?

[PEDA] A DXP annotation feature?

2004-03-17 Thread Ray Mitchell
I don't use DXP myself but a coworker here has no choice since 99SE won't 
work on WinXP.  Anyway, when it came time to annotate his schematic to get 
rid of all the question mark designators he went through the standard 
procedure.  When it was done he found that several schematic symbols had 
been arbitrarily moved to other pages and plopped down right in the middle 
of nowhere!  In addition, some existing symbols had been duplicated and 
placed in arbitrary places on arbitrary pages.  Therefore, his solution is 
to simply go through all 12 pages of his schematic every time he annotates 
in order to correct DXP's errors (or should this be considered a 
feature?).  Has anyone seen this behavior?

I don't use DXP myself but a coworker here has no choice since 99SE won't
work on WinXP.  Anyway, when it came time to annotate his schematic to get
99SE has been running fine on XP Pro here for ages.
That's encouraging to hear.  Many of the people here have not been able to 
get it to run.  In fact, many of them have gone back to Win2k just so they 
don't have to downgrade to DXP.  I'll pass this on to them.  Thanks.

Re: [PEDA] 99SE: 2 of every net name?

2004-03-17 Thread Ray Mitchell
Mike,

I don't understand what I need to do to clear all nets.  I told it to 
un-route (although nothing had been routed).  From within the PCB editor I 
then told it to load all nets.  It indicated that there were many redundant 
nets.  I told it to execute and it proceeded to remove all nets and all 
parts.  It's a good thing that the UNDO works!  I've placed many of my 
components already.  Does this mean I must redo all of that?  If anyone can 
tell me the format of the offending portion of the .DDB file I'm not 
adverse to using a binary editor on it.  This approach is probably way too 
complex for the average person, though, since it's obviously too complex 
for the Protel developers themselves.

Thanks,

I've never seen this before.  In 99SE (Win2K) I've created a schematic and
am starting the PCB layout.  When I double-click on a pad and look at the
net attached to it, as well as all the available nets, I noticed that there
are two of every net.  For example, there are 2 A5 nets.  Some of the A5
pads are connected to one of these nets while others are connected to the
other, even though they all have the same A5 name.  My manually going
through all the pads and selecting, for example, the first A5 of the pair I
can get all A5 pads to connect together, etc.  Any ideas?

Re: [PEDA] Common PCB footprint specifications

2004-03-11 Thread Ray Mitchell
Everyone,

Thanks for all the responses on footprints.  This whole issue is pretty 
sickening actually.  Since we produce low quantities of diverse products we 
have no dedicated PCB layout people.  All engineers do their own circuit 
designs and parts specification and ultimately are expected to do tiny PCB 
layouts of everything and get them to work.  The thing that gets me is that 
it seems like it would be extremely simple for parts vendors to provide 
land patterns for their parts along with the mechanical drawings of the 
parts themselves.  Some do but most don't.  I just talked to Maxim about 
this and they said they simply don't provide this information.  They 
recommended IPCSM782.  Of course a good percentage of the parts you need 
are not listed in this document and a lot of them that are there do not 
match the recommendations of the vendors of the parts.  I asked Maxim how 
they layout their own eval boards since they provide no guidelines and no 
guidelines exist in IPCSM782.  They didn't have an answer but I suspect 
they rely on rules of thumb and intuition, which is what we end up doing 
with our designs here most of the time.  After enough bad yields and 
scolding from our PCB fabricators we manage to stumble into something that 
seems to work.  I did find what I thought was a good layout for 0402, 0603, 
etc. from AVX capacitors.  Upon closer inspection, however, I found that 
their recommended footprints violated their own guidelines given on a 
different page of the same document.   Go figure!

 Subject: [PEDA] Common PCB footprint specifications

 Hello,

 I'm sure this is a repeat, but is there a simple
 specification readily available that gives the commonly
 accepted (if there is such a thing) dimensions for 0402,
 0603, ..., SIOC-14, etc., and all the other standard
 footprints?  I don't really want to wade through a bunch of
 technical stuff to derive all of this myself and I certainly
 don't want to trust a priori the patterns that come with
 Protel or any other product.  It's really annoying when part
 manufacturers don't provide these footprints, assuming they
 are common knowledge.
Ray

I have accumulated quite a library of such footprints but most of them
will have been optimised to suit our in house processes more than
following the IPC standards.
The supplied Protel IPC land patterns are not too bad, they are
certainly a good basis to build your own on. But most libraries stop at
the land pattern stage, which is what the IPC are looking to change.
A lot of the way the IPC are trying to structure library conventions are
along the lines of what I was already doing for years anyway, not
because it is good, but because it make life easier for us internally if
the naming conventions for footprints already match vision library
footprints on placement machines (which then relates to mechanical
dimensions as well, as a Murata 16V X7R 0603 will have different
dimensions to a Kemet 16V X7R 0603 in same voltage) and other EDA
packages we use etc.
I especially like the way the new IPC recommendations take account of
things like, 0 deg positions in tape or tray, if Protel could also make
allowances for rotation on non-polarised chip parts (only use 0,90) to
reduce un-necessary head rotations on turret head placers that would be
even better as I currently use an in house utility to parse the PP
files and check for string matches on footprint  part number to
identify non-polarised parts and it will replace 360 or 180 values with
0 and 270 values with 90.
In DXP I planned to use a parameter for that at SCH level, so I only
need to check for one match, but that's another story, no time for
documenting or agreeing how this should be done internally yet.
Same with pad sizes, I slightly oversize SMT pads in some cases against
IPC recommendations (not much) to allow for place tolerances when
reducing Z height  down pressure, Vac release and place speed,
especially on Chip r/c's as well as wave flow direction and so on.
Same for connector placement, especially for IDC and connector rows
2.54mm, I sometimes enlarge the pads beyond IPC recommendations in one
direction to get the best out of the features on our wave soldering
equipment (Vitronics-Soltec with Select-X debridging).
If Protel could assign a different footprint for rotation, or side,
based on some sort of logical system, then it would make life so much
easier to define DFM rules even at SCH level.
Perhaps that's worth a new feature request on the DXP forum :)
To me a library has to be more than just a symbols collection, or the
manual pre-processing required diminishes its value, very little third
party libraries do this, so IMO are not worth it.
I like the IPC new offerings for library recommendations very much, and
would like to see it adopted

The above is just some thoughts of mine, Ill skip the temptation to rant

Re: [PEDA] New PC tested with Protel for at least 1 month now...

2004-03-10 Thread Ray Mitchell
I'm glad to hear someone has had good luck with ASUS.  Some time ago I went 
through several ASUS 400MHz CUSL2 motherboards, different CPUs, different 
brands of memory, different power supplies, and everything else to try to 
stop random crashes.  It wasn't just with Protel either.  I finally ended 
up slowing the memory bus down to 100MHz even though everything was spec'd 
at 133.I'll never touch ASUS again.  I was using Win2K.

Has anyone had any problems with Protel with Intel motherboards?  I've 
heard their not barnburners but are extremely stable.

I'm sure if I added 1 card to the PCI bus, the boot time would probably

suggestions are welcome.
I have done this, but it gets a bit messy.  I'm not sure my method is 
actually any improvement.
The only thing I found that worked was VHDL (architectural) netlists. An 
annoying bug
is that P99SE Sp6 will only output one VHDL netlist, then you have to 
restart P99.
If you don't restart P99 each time, it will hang on the netlist step. If 
you wait half
an hour, it outputs 65536 lines of garbage before the valid netlist.

But, you get a netlist almost ready for Xilinx isp.  You have to manually 
add the library
unisim and the line use unisim.vcomponents to get the use of those 
library components.
You can edit away the _sch extension from all VHDL files made from 
schematic sheets.
You have to manually remove duplicate component declarations for all of 
the user-created
components.  This only comes up on sheets where you have placed the same 
user-created library
component multiple times.

The rough edges are that P99 wants input and output pads on the top level 
page for sim
and ERC, but Xilinx DOESN'T want pads, it assumes any ports on the top 
page are
pads.

Jon
Jon,

Yes, messy but not as messy as trying to use the ISE 6.1i abomination that 
they're trying to pass off as a schematic tool.  From what you describe it 
seems like it might be reasonable to write a small program to post-process 
the Protel VHDL files to massage them into a form that ISE wants.  If you 
don't mind, I'd like some clarification on some of the things you 
mentioned.  When I created XNFs for ISE 3.1i Design Manager in the past I 
had to create a Protel .PRJ sheet that merely contained Sheet Symbols with 
Sheet Entries.  The actual logic was on the .SCH sheets and was tied 
together by the .PRJ sheet.  I always found it annoying Sheet Symbols were 
needed since they're not needed when doing a schematic for a board layout.

I'm most confused about your last statement and I'm not sure what you're 
telling me about pads.  I've always used them for my FPGAs in the past for 
XNFs.  Are you saying that now I should just use IBUFs and OBUFs as my 
entry and exit components and not attach IPADs and OPADs at all?  I didn't 
think Protel itself cared anything about IPADs and OPADs since they are not 
used in board schematics.

Am I correct in assuming that you regenerated all of the Protel library 
components for Xilinx as VHDL files also?

[PEDA] stackups - Capacitance - Book Recommendation Wanted

There are obviously a lot of analog things to worry about when designing 
a fast, dense digital board.  I fought a large digital board I did through 
3 iterations by simply trying different things without fully knowing what I 
was doing.  It eventually worked but I don't know if my next design 
will!  I would appreciate it if someone could recommend some books on high 
speed board design that cover topics such as stackups, capacitor 
resonances, trace thickness, and any other important issues.  Of course, I 
would prefer a cookbook approach if possible since I don't want to get 
into the heavy math of it all if I can avoid it.

Re: [PEDA] six or eight-layer (or more?) stackups - Capacitance

 I thought that the following stackup was prefered because then every

But then you don't have as good decoupling between your pwr and gnd planes,
since they are farther apart.
My stackup (as mentioned in an earlier post, and repeated below) gives you
copper balance, better decoupling, and your signals are still only 1 layer
away from a pwr or gnd plane.  And since the pwr and gnd planes are
effectively the same thing to high frequencies, a signal being next to a pwr
plane is the same as that signal being next to a gnd plane.

While we are on this subject, I like to use 0.01 uF caps for decoupling, not
the 0.1 uF caps you frequently see on digital circuits.  The reason is that
0.01 uF caps have a higher self-resonance frequency than 0.1 uF caps, which
makes them better able to decouple the high-speed transients that are so
common in today's circuits.  Also, 0.01 uF caps are less expensive and take
up less space (0805 vs. 1206).
First, my experience regarding layout is minimal at best since I seem to 
exhaust all the wrong ways first.  I once took a class in multilayer layout 
and was told that the capacitance between the power/ground planes 
themselves was sufficient for decoupling high frequencies and that adding 
capacitors could cause tuned circuits and troublesome resonances.  I'm 
simply asking, any views on that theory?

[PEDA] How to copy Protel schematics into other documents

2003-01-23 Thread Ray Mitchell
Everyone,

Several months ago I posted to this newsgroup requesting information about 
simply using Protel 99SE as a nice schematic drawing tool with the ultimate 
goal of being to incorporate the drawings as an imbedded objects in other 
applications such as Microsoft Word.  I only wanted the schematic part and 
not the border and extra space that might surround a small drawing on a 
large sheet.  At the time I either misunderstood the responses or somehow 
got the impression that it couldn't be done reasonably.  As a result I 
looked around for other schematic applications that would permit this.  I 
stumbled upon CircuitMaker 2000, which will let you export drawings as a 
.wmf files.  However, in my opinion it has the absolute worst GUI interface 
I've ever encountered in modern times (yet they actually charge real money 
for this product).  As a result I decided to fool around with Protel some 
more.  I found the following, which many or all of you probably already know.

1.  To copy and paste the entire drawing sheet simply select the portion of 
the schematic you want and copy it to the clipboard using ctrl-Insert (or 
equivalent).  Then go into your other application and paste it there.

2.  This still does not address the issue of the sheet border being part of 
what gets pasted or the issue of empty space surrounding your drawing.  To 
get around this:

A.  Paste the desired section of the schematic onto the lower-left corner 
of a new Protel schematic sheet by itself.

B.  Double-click the border of the new sheet to bring up the Document 
Options dialog box.

C.  In the Document Options dialog box uncheck all the boxes you don't want 
on your copied drawing, such as Show Border and Visible Grids.

D.  Check the Use Custom Style box and enter the dimensions of your drawing 
without leaving excessive space around it.

E.  Click the OK button and copy and paste as described previously.  Neat 
isn't it!

My wish list on this is that:

A.  Rather than the pasted object being a picture, it would be whatever 
is necessary such that double-clicking it within in the target application 
would reopen the original Protel schematic for editing.

B. It would be nice if within Protel you could merely drag the edges of a 
sheet to a new size rather than having to go to the Document Options dialog 
box and actually type in the new dimensions.

[PEDA] Long overbars on printed output

2002-09-05 Thread Ray Mitchell

Hello,

I'm using Protel 99SE w/SP6 on Windows 2000.  Many of my schematic symbols 
(from the Protel Libraries) have overbars on the low-true signal 
names.  When viewed on my monitor they look fine but when I print the page 
all of the overbars become several inches long, extending out of the entire 
symbol itself in many cases.  This totally destroys and confuses the look 
of the printed schematic.  I'm using an HP 4MV in landscape mode for all 
printing.  I imagine this must have something to do with a printer font 
problem, although everything else I print other than Protel schematics 
comes out fine.  Any ideas or specifics on how to remedy this?  How about 
if someone invents something, maybe we should call it WYSIWYG, so that what 
you see is what you get:-)

Thanks,
Ray Mitchell

Re: [PEDA] Long overbars on printed output

2002-09-05 Thread Ray Mitchell

Tony,

My printer is configured as a simple Ethernet IP printer.  Several users 
here tried the HP Jet Admin stuff but it never worked properly.  I'm not 
clear on the printer driver business, though.  If a printer is networked 
does each user still need to fool with printer drivers on their individual 
machines or is the printer driver somehow now attached to the printer 
itself?  Actually, the long overbar problem just started.  I'm not sure 
when, however.  I'm beginning to wonder if Win2K SP3 might not have caused 
the problem, or possibly one of the other multitudinous periodic updates 
that Microsoft comes up with.

Hi Ray,

The long overbars used to be a problem (for me) quite a while ago. I'm
not sure when it was fixed, but I'm looking at several examples of 11x17
prints I did with my HP4MV and there are no problems. Possibly the
printer driver??? I have my 4MV setup on ethernet, so I have to print to
an IP address using HP's oddball driver. I used to have more problems
with Win2K and the older jetadmin s/w, but now I'm running XPPro and for
some reason the new jetadmin for XP seems to be much smarter. (I'm sure
I could have installed the new jetadmin on W2K but I didn't for unknown
reasons)

There are a zillion parameters to the printer driver. You might want to
mess around with them. Font substitution table, output protocol, etc. I
don't know if any have an effect on what you're seeing.

Re: [PEDA] Long overbars on printed output

2002-09-05 Thread Ray Mitchell

Yes, that's how I printed the bad ones.  I just tried it again but opened 
them all first and it worked correctly.  Should Protel classify this as a 
feature and charge more for it, or as a bug and fix it (or maybe just 
punt)?  Thanks to everyone for your help.

[PEDA] Print/Preview Problem

2002-06-05 Thread Ray Mitchell

I'm using Protel 99SE with SP6 on Win2K.  I can create a .PPC from a .PCB, 
play with it, print it out, etc. without a problem.  However, when I go to 
another project then return to my .PPC, or close Protel then reopen and 
return to my .PPC, although the .PPC is still there it appears empty.  I do 
a Browse PCB Print and it still lists all the correct layers I originally 
set up, but they simply don't appear.  I do a Rebuild but nothing 
happens.  Finally, I discovered that if I do a Process PCB the selected 
layers reappear but the page has been shrunk down to a very tiny size.  I 
must change the view to get it back to where I started.  Is this a bug or a 
feature or am I simply doing something wrong?

Thanks,
Ray Mitchell

[PEDA] Merging libraries?

2002-01-30 Thread Ray Mitchell

(Protel 99SE)

Over the years I've created many Schematic and PCB libraries and as fate 
(and sloppy programming practice) would have it, I've ended up with many 
duplicate or semi-duplicate parts in different libraries.  I'd like a 
reasonable way to merge everything into one library.  Ideally, if a 
duplicate part were found I'd be given the option of which one to keep.  Is 
this asking too much?

[PEDA] Getting a .wmf figure to reload automatically

2002-01-24 Thread Ray Mitchell

Hello,

I'm using Protel 99SE/SP6 on Win2k.  I have created several custom drawing 
templates for schematics and some of them contain a reference to a .wmf 
file containing our company logo.  When I first created the templates the 
logo showed up fine, just like I wanted.  However, when I shut down then 
bring everything back up all that shows up in place of the logo is some 
text claiming the .wmf file is not available.  If I fool around with things 
(I'm not exactly sure what I actually do since it's more trouble than it's 
worth) I can get the logo to reappear, but the next time I open up the 
project the logo is gone again.  I've tried placing the logo file in the 
.ddb file as well as placing it in several different directories but in all 
cases it simply won't appear on the appropriate sheet consistently.  Any 
suggestions?

Thanks,

[PEDA] Consolidating Schematic/PCB Libraries

2001-11-01 Thread Ray Mitchell

Over time I have ended up with several different versions of the same 
schematic library as well as several different ones.  As I look through 
them I notice that some contain different versions of a part but with the 
same part number.  In addition, the same library might contain different 
parts having the same part number.  Although I agree that I should have let 
my libraries get into this mess, the fact is that they are already in 
it.  My question is twofold: 1.  Is there any automated way to merge 
multiple libraries into one, hopefully with notification of duplicate 
names?  2.  Is there any automated way to detect and eliminate, with 
notification, duplicate names from the same library?

Along the same lines, is such a tool available for PCB libraries too?

[PEDA] Using equations rather than logic gates?

Is there a (reasonable) way to enter equations into the Protel 99SE
