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*.

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

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. If that was the =
kind of chip I was doing, I=92d do those straight in HDL, not draw them =
in gschem. In any case, there=92s nothing preventing you giving a net a =
name that describes a bus, and dealing with that downstream.

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).
