Hi Facundo,

I've been looking at your design, and it's making my machine fall over too.
The problem appears to be that the design hits some worst-cases in
gnetlists algorithms.

Unfortunately, there appears to be two options:

1) Rewrite gnetlist.  Unfortunately, it appears that the people who are
sufficiently familiar with gnetlist to attempt this don't have much time
right now.

2) Rework your schematics along the lines suggested by some of the other
people on the list.  For example, you could netlist each level separately
to a SPICE module, and then combine them at simulation-time.

Good luck!

Peter
