Hi there, did anyone have problems with the LVS of poly-resistors or mim caps? I have a simple RC circuit with 3 high po resistors (one in series with two in parallel) and then a MiM Cap in series with the total R. If do the LVS with netgen for only the resistor it works fine, but when i attached all the components togheter netgen crashes. Is there a way i can get more info about hte crash? It just says segmentation fault, core dumped

If it's a simple circuit, then post the two netlist files that feed into netgen, and I can figure out why it crashes (and hopefully do something to prevent it).

the *_lvs.spice file is the extracted one. I have tried just with one resistor and netgen worked fine. But as i connected 3 resistors together (one in series with two in parallel) it crashes.

Other than not matching, it works for me without crashing. What version of netgen are you using?

Yes, probably. The current version is 1.5.188.

So, I've just updated all the tools & the open_pdks. The segmentation fault problem still happening. Is there a way to get any more info about the crash?
