Subject: | [geda-user] Converting schematic from OrCAD to gschem |

Hello Community, I am building a GSM modem board based on a certain obsolete chipset from a little over a decade ago. I am using the chip vendor's reference design as my starting point. The chip vendor (who no longer make these chips and want nothing to do with them) used OrCAD for their schematics, but for my board I would like to use gEDA. My question: is there any way to convert a schematic drawing from OrCAD's proprietary binary format (.dsn) into gschem other than manually redrawing it from scratch based on a paper printout of the original? I found the historic DSN file here: ftp://ftp.ifctf.org/pub/GSM/Calypso/Leonardo_rev05.dsn There are also a few Leonardo_*.pdf files in there, containing PDF schematics for 3 slightly different versions of their board. 3 different PDF versions, but only one DSN - and I'm not even sure which of the 3 the DSN corresponds to, as I have no way to open or view it. The parts of the circuit depicted on the "200 Baseband Chip-Set" and "600 Rita QB RF" sheets will need to be copied almost verbatim from the reference design to mine, so I would really like to simply "import" these sheets from the OrCAD drawing, if possible. If no scripted conversion of any kind is possible, the fallback would be to redraw all of the symbols and nets on those two sheets manually in gschem, based on one of the PDF versions, but I'm hoping there might be some better way... TIA, Katya
