gEDA-user: symbol
Hi, I've created a symbol using tragesym. When I place the symbol on my schematic, end press `ve` sequence gschem zooms a waay out. So I suspect that there is something wrong with my symbol. There might be some hidden element in it. I've opened with a text editor, but found nothing. The symbol is attached. Could anyone check it?

My requirement is a 21 pin connector which has staggered pins like DB25 but with numbered serially i.e. staggered, unlike DB25, which has row-wise numbering. Also pin spacing is 100 mil instead of 50 mil in DB25. So, I tried editing coordinates and numbers in the 25f.fp file. This did not match with numbering in symbol file which was also edited, suitably. Finally relocating Pin ElementLine in the order of pin numbers(desired) and changing the numbers in quotes also in the same order, worked as solution. Iam attacing both the edited files. I request help confirming this editing has no loopholes. BTW, is there simillar connector in newlib folder. I do not notice any. My versions are gEDA/gschem version 1.4.0.20080127 PCB version 20080202, default package version of Ubuntu 8.10. Will upgrading to 1.4.3 help? vsrk sarma I do not fully understand your problem. If you have to use an other device, you have to modify the footprint. You have done this. Have you done this with pcb or with a texteditor? Modifying pinnumbers is easy with texteditor, moving pins needs calculations. Maybe your problem is this: The shape of gschem symbols has absolutely no meaning for the pcb layout. The connection is done only by pinnumber. A pin in symbol with pinnumber 7 is related to pin 7 in footprint file. If you connect something to pin 7 in the schematic by a net, then this connection is mapped to the footprint pin. Only by pinnumber, not by shape. Maybe one of the other subscribers to this list will understand your problem better and will answer your later.

Going to layout after you have already decided the best general position for parts makes it much easier. The second reason is that later on it will be easy to look back to a schematic that has a similar layout as the board and the same pinouts. We'll have to agree to disagree. When I look at a schematic, I want to be able to quickly and easily work out what the circuit is designed to do, and having the pins on my symbols arranged by function and bus offset rather than by physical position helps a great deal. What you're doing completely defeats the point of having separate schematic and layout diagrams, IMHO. What do you do about parts that have different pinouts depending on what package they're in? Peter Of course you use the place the part on the schematic with the pinout you are using. When you are troubleshooting a circuit with a scope or analyzer, it adds an extra decoding step to have the pin order scrambled. And it really is annoying when you're trying to look at the schematic to see where your 64-pin micro has an unused pin free. I always use a layout with proper netnames when working off of a board, then got to the schematic for the general idea. it's easy to find extra I/Os when you name its net spare_IO_x selected them in the netlist and highlight them in layout, really easy :-) cause I hate counting pins or balls. This argument works for low pin count parts, it fails with high pin count parts. For FPGA's we make customized symbols when the pinout of the device is I/O mapped. The usual problem with having the pins in IC-order is this big rat's nest of wires running around the chip to get to the pin. But a better solution than moving the pins around is using named nets / ports. This also helps make the intended function of the circuit more explicit.
