Did the stuff from the 80's support every downstream flow gschem supports? Every possible layout program, every simulator, ASIC design, too? > *sheesh* There may not be any single "right" way to do it. > But there are certainly ways. Yes, and this is a non problem. There are several mental poisons you must purge from your head, and then the problem disappears: Poison #1 is the idea that you should directly instantiate library symbols into your schematic. Use a project library instead. Poison #2 is the idea that a single symbol can conceivably represent every package and flow. Customizing symbols is the solution, and is unavoidable. Poison #3 is the idea that you should do everything inside the tool. gEDA is a toolkit: its strength is that it plays well with other tools. So, use them. Easy to fix pin numbers in a text editor. Now, what *I'd* really like is the ability to draw generic subcircuits without part numbers, footprints, pinouts, or values, and choose these downstream. But that requires a refactored gnetlist, I think...
