Hi All,
I am evaluating gEDA and came across one feature I am extensively
using today with a commercial EDA tool when dealing with large
components, like SOC, FPGAs and ASICs: heterogeneous symbols.
I searched the doc, the mailing lists and the Web but could not find
how I could create and use such symbols with gschem and gnetlist.
As Roger Williams defines it in his post: http://www.geda.seul.org/
mailinglist/geda-dev6/msg00003.html
Heterogeneous devices are non-identical symbols that represent
different parts of the same device for REFDES and layout purposes.
They can be tied together by the same 'HETERO=DEVICE1,DEVICE2...'
attribute on each device. Typical examples include:
- large complex logic devices split between multiple symbols
because of space constraints;
- multi-function devices split so that each different functional
block has its own symbol (relays, for instance);
Does gschem support such a way to deal with large devices?
If the answer is yes, then how?
If the answer is no, then how are people dealing with it?
Thanks,
_jP
