Oh, I made a mistake. Of course, the components are renamed by
refdes_renum and not by gnetlist! Didn't use gnetlist on that design
because my progress has stalled since then.

Never made it to running gnetlist because the refdes problem is a
show-stopper. But when looking at the gTAG example I found out that
gnetlist has many options to make the netlist for your needs out of a
hierarchical design.

Do I really have to run refdes_renum on the subcircuit only?
Is there a tutorial about subcircuits on the net explaining all the
steps in detail?
