Re: [PEDA] multi sheet problems
Bob, Two points about this -- 1) The list of footprints in the library symbol is merely possible choices -- you don't have to use any one of these. So changing the footprint list in the library should NOT update all the footprints for those symbols in the schematic. 2) Use global edit if you really want to change all of them to the same (new) footprint. -Original Message- From: Bob Wolfe [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 20, 2001 6:15 PM snip I do however agree with the person talking about how Protel updates board and schematic from library, it is a little less than I had hoped for in my setup. I really wish the footprints would REALLY update all symbols from the library. It does but it will not use those new footprints on a board you need to go into the schematic for each unique part and force it to that new footprint. ie if you get properties of the symbol you see a pulldown menu for footprint which now does contain the new part too BUT until you select the new footprint you will still see the old footprint on the board.

Re: [PEDA] Intelligent SCH and PCB components
Sounds like way to much confusion to me. I don't mean that you always have to use formulas. I wrote: 'What we need is the option of using formulas and expressions' What I mean is that we can do the job in the usual way, but for the exceptions and the specials it might be helpfull. We do have the option to use Client Basic in Protel, it is not necessary to use it, but you can do nice things with it. Take a look at the several usefull things which are written by Brian Guralnick. The same is true for Excel, it is possible to use it without programming and difficult formulas, but if you take some time to learn how to use the 'difficult' things it will pay-back. Do your production boards change that drastically from the proto? Our's certainly don't. No, I like proto's which are almost equal to the production type. But sometimes we use the same PCB for 2 production types. I don't want to remember which parts on the BOM are needed for type A and/or type B. If all the 'inteligence' is in the schematic and components, then I don't need to rely on my memory if the project needs a revision. The intention of the 'examples' was only to explain the idea.

[PEDA] Want to know which program created some .PCB files
Hello all, We have been given responsibility for a large suite of technology from a defunct US company (once owned by Cadence). The schematics are in OrCad capture (DSN) format, but the PCBs are unknown. I thought either OrCad Layout or Cadence Allegro but neither creates *.PCB files. Inspecting the binary PCB files gives no apparent clue (no helpful text string embedded anywhere that gives any clues). So what mainstream, and probably high end, programs create PCB files with a .PCB extension. I have reason to believe that it was hosted on Windows but even it may have been a Unix variant. It is not an option to send out a sample file (at least until we get through the pile and find some of the low-IP test jigs). Not much to go on I know but has any one got any ideas?

Re: [PEDA] multi sheet problems
Dwight, I believe it is the first one on the list of footprints it will actually put on the board. And the only one it will automatically put on the board. In my situation I would really like an option to update automatically in one shot all of the footprints in a board to what is in the library. I did talk to Protel about this and I understand their relunctance for this. It really is my situation. Using global edit is still too much work. I am taking in an Orcad schematic and what is in the footprint field on Orcad side is absolutely not what I want for footprint names and I can't get the person on the other end to change this. I am looking into mapping some other field in Orcad to the footprint filed in Protel, but been to busy to really look into any other options at the moment. Unless you hav eany other suggestions I really want the system to automatically see my footprints for the same symbol part number not his coming in from Orcad.

Re: [PEDA] Meetings
I understand that the user group started with local meetings in the San Jose California area, but there have not been actual meetings for a long time, except for a few Protel-sponsored meetings at PCB Design Conference West and East. Worcester is about an hour away from me and I'd be happy to attend a meeting in that area or even as far east as Boston. Local users are obviously free to organize meetings wherever, and I see no harm in using this Forum to publicize them. If it ever happens that local meetings become so numerous that publicizing them internationally on this list is a burden, we can use a calendar page on one of the protel-users lists on yahoogroups.com. I'm also willing to attend user meetings outside the Mass./Conn. area, but I might be looking for expenses It would be good for a local meeting to have a company sponsor which would provide a meeting place At 10:15 AM 12/21/2001 -0500, Sean James wrote: Has anybody ever thought about having local meetings for Protel users?

Re: [PEDA] Good Dual head video card combination for Protel.
I had my Matrox G400DH with my dual PIII 450Mhz Intel based mother board for 1.5 years. The only problem I had was games did not play too smoothly. If you tell me what your system configuration it, I can solve your Matrox headaches.

Computers are cheap, really cheap, at least single-CPU computers are, so if I were so flush as to have a Specctra license, I'd seriously think of setting another box next to my system, putting in a keyboard and monitor switch -- unless I had extras and room for them -- and running Specctra on that. The network is the computer is a bit trite now, but I just upgraded my old 10MBPS ethernet to 100MBPS, which I should have done quite some time ago. In fact, I am upgrading everything, I intend to write about it. Prices are *really* good, it's a buyer's market.

Re: [PEDA] Project woes
At 02:36 PM 12/21/2001 +1100, Thomas wrote: I have a 5 sheet project that I was planning to put on one PCB. However It has become clear that there is no way all the parts are going to fit in the space available. To solve this I will have to stack 2 PCBs (there are mounting slots provided for two PCBs in the enclosure). The problem is that the most efficient way to do this requires all the display parts on one PCB - the rest on the other. Unfortunately this is not the way the schematic sheets are arranged. So it will be impossible to get a netlist for individual PCBs. What you want here is one schematic and 2 PCBs. Not necessarily a great idea unless the boards are truly conjoined twins, which is not the case if I understand the description (two mounting slots) What I was planning to do was draw the two pcbs in one file connected together and have a perforation or groove for splitting the two pcbs. You could do this. In this case, you have not two pcbs but one. Only they get cut apart and the tracks cut replaced by ribbon. If you like, the interconnection tracks could be on a non-fabricated inner layer, so you won't even have the embarrassment of cut copper at the board edge. Placing correctly sized vias on a 2.54mm pitch for PCB interconnections on both PCBs should allow me to use a ribbon cable from another one of our standard products. Don't do it that way. Instead, add connectors to the schematic, two of them, matching the ribbon, even if the connectors are only a hole pattern for flat flexible cable or the like. A pattern of correctly sized vias I would call a footprint, and you can control this from the schematic if you place connector symbols Plus you probably already have the footprint from your other standard product. I plan to annotate the schematics showing which parts are on the second PCB. All this should still be quicker than redrawing the project. You are going to have to decide what parts go on what PCB, and then ensure that the relevant signals communicate on the ribbon. That takes time. You might as well split the design into two parts. Seriously, that is probably the easiest way to do this. I recommend this: take your existing schematic, and save it with a different name. Then split the original design into two schematics, you can use select, cut and paste to move parts and interconnection information from one to the other. Be careful about multipart ICs, if you have any! Be sure to place the interboard connectors, one on each schematic; it may be best to assign nets to the pins with net labels. When you are done, add the two connectors with their net labels to the original schematic and generate a net list, I'll call it original.net. You will probably want to use net labels and ports global. If you have used some other scope for your original schematic, things get more complicated, I won't address that here. Take your individual schematics and link them through a top-level project schematic. Make a project netlist, I'll call it split.net. Once again, net labels and ports global. Use the Protel netlist comparison tool (It's under Reports in Schematic) to prove to yourself that both netlists are identical. If they are not, you have something to fix Then design each PCB, one from each of the individual, non-linked schematics. At this point you can choose to fab them separately or together. (If you fab them together, you may want to add the dummy interconnections on an unused inner layer I mentioned above, that way the whole design will DRC properly). If later you change one of them, you can just fab one instead of being forced to fab both at higher cost. Also, with the individual sheets, you will be able to generate a BOM for each board, pick and place, etc. [EMAIL PROTECTED] Abdulrahman Lomax Easthampton, Massachusetts USA * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Re: [PEDA] special board requirements ??
At 10:34 AM 12/21/2001 -0500, Robison Michael R CNIN wrote: is the 1-to-3 relationship between via width and via depth the same for a thruhole pad? From a fabrication point of view, more or less, a via = a thruhole pad. The plating process is the same. On the subject of cost, it sounds like it may be possible to fab this as two single-sided PCBs plus one blank. In other words, cheap. All boards would be drilled with the same holes, unless you want vias on one board only (in which case you have one or two two-sided boards on the outside). Still, you are falling into a standard fab type, you can use Advanced Circuits protos for example. I.e., supercheap. Properly designed matching holes on the boards can be used as tooling holes, so registration accuracy between the two sides would be almost automatic.
