Those of us making truly hierarchical netlists for SPICE and Verilog use =
a separate gnetlist run for each module. But there=92s a missing tool. =
It=92s hard to automatically figure out what goes into a design: =
geda-gaf has its search rules, but their application is hidden. It would =
be really nice, for a variety of purposes, to have a tool that takes the =
top level schematics for a project and generates pathnames for all of =
the source files, partitioned according to their use in the hierarchy. =
This would be useful for a number of purposes including, but not limited =
to, hierarchical netlisting.
I should investigate whether the gaf utility could be used as a =
foundation for such a script.
