I've got a project coming up which I'd like to run through DXP as a
learning project, since it's not too urgent. While I do have a huge
archive of DXP emails from [EMAIL PROTECTED], which I could
no doubt work my way through, are there any other resources out
there to help the transition?
My preference is to use functional pin designations something like
k1a2
a1 k2
or
d
s g
or
c
e b
SOT23 devices, connectors, and diodes are the most common errors I have made
in my 18 years of layout work. A package change because of power,
availability, or
an alternate manufacture can

personally, i oscillate between liking the 1 2 3 convention
and the E B C convention
like many things 'it's all bad'
i once had some T1 3/4 LEDs from HP
the short leg was the anode for that *particular* p/n
which is why they weren't very bright when installed

Steve- I recently finished a large project (DXP sp2) learning as I go.
It wasn't that bad. This forum was a huge help, better than any thing
else I had found. The only thing I could tell you, other than well known
things like the auto-router being useless, is to dive right in. I found
it to be
Steve- The only place I've seen the 2004 name used is on Altium's web
site and marketing materials. The program's splash screen and about menu
all call it DXP. I think the marketing whizzes at Altium came up with the
2004 moniker to make it appear to be a new and better product. I wish

You are facing a learning curve when you move to DXP or to 2004 (the
magnitude of the learning curve is in dispute, but everyone except
Altium agrees that it is there). Why waste your time learning an
orphaned product? You get 2004 for free if you bought or downgraded to
DXP. If you have
How can they forget the smoke and mirrors when it represents such a
large portion of their recent submissions of 'intellectual property?

I've used Protel since the V1.1 days. We stopped upgrading after buying a
couple of licenses for 3.x, mainly because it does about 99% of our needs.
I've had cursory looks at other versions as they came out, but nothing
really grabbed me. Now I'm looking hard (using a trial cd with SP2), but I
I have no experience with DXP but I can recommend the move from v3 to
99se.
I have found 99se +sp6 running on win 2k is extremely stable and the db
system is very useful to us. Conversely I had no end of trouble with v3.
Most of our boards are double or 4 layer at most and easily manually

Dennis,
The pin numbering can only be 1 2 3.
Mira,
In Protel, pin numbers do not have to be numbers, they can be letters. So
you can use E,B,C for numbers if you want. If you have very commonly used
parts making a matching set of Sch and footprints with

You said

Is there a 'classic' setting somewhere?
The library panel really irritates me. It could be so much better.

Hi Ian,
I understand your point but I meant that
3
1 2
was the way you count the pins and it also showed the
direction.
I thought we were talking in general becasue 1 2 3 can
be also
2
1 3
What function will be attached to these pins depends
on the component and it can be a letter or a number
Ian,
No the various Pinouts of the SOT-23 are unfortunately not obsolete. I wish
they were. Sure they are all 3 pin devices, but they keep playing musical
chairs. Always check the data sheets.

Hi Phillip,
Could you just elaborate a little on
The automatic generation of the *entire* FPGA's schematic sheet,
drawing all the wires, assigning nets to the wires, creating
the off sheet ports, creating the pin constraints file, and the FPGA pin
assignments can be passed
when we say 'different pinouts' are we talking about the
the geographical location of the given pin function or are we talking
about the pin *number* assigned to the given geographical location ?
it makes a difference!
anyway what is clear from this dialog is that we all care about what
we do

quite a bit harder to deal with in the case of SOTs though
