What do you imagine IC = designers need? I design mixed-signal ASICs in gschem, and do not = perceive any limits. Just another application for a complete, general = purpose network topology editor.

How about libraries that you can download = that don't have naming collisions with other = libraries?

Since you have = complete control of your library path, why is this a problem? Just put = together the library *your* project needs. No big deal. Certainly not = something that requires a new *feature*.


How about complete hierarchical design support = with uniquification?

I=92m = not sure what your problem is. My ASICs are hierarchical (of = course).


How about = Busses? IC's need support for wires,vectors and busses. Gschem does = wires with some graphic support for vectors but nothing for = busses.

Need? Maybe they = would be nice, but I haven=92t really missed them. Mostly you want them = in complex digital parts, I think.

Gschem = supports small data designs. IC designers need support for big data = projects.

Big data = designs are sanely composed of small data components. Gschem handles = those small data components well. Drawings don=92t scale well to big = data, so gschem isn=92t the right tool for the higher levels (which are = more like programming than graphical design).
