RNetExtractor internal error #2102
Description
Hi @klayoutmatthias,
I get an internal error
RuntimeError: Internal error: src/db/db/dbPLC.cc:461 i != v2e.end () && i->first == v && i->second != mp_e.back () was not true in RNetExtractor.extract
It can be reproduced with this script:
from typing import *
import klayout.db as kdb
import klayout.pex as klp
# reproduce internal error of RNetExtractor
# single NFET example

POLY = 20
LI1 = 21

tech = klp.RExtractorTech()
for l in (POLY, LI1):
c = klp.RExtractorTechConductor()
c.layer = l
c.resistance = 1000.0
c.algorithm = klp.Algorithm.SquareCounting
tech.add_conductor(c)
for cut, bot, top in ((LICON_POLY, POLY, LI1), (LICON_NSDM, NSDM, LI1)):
v = klp.RExtractorTechVia()
v.cut_layer = cut
v.bottom_conductor = bot
v.top_conductor = top
v.resistance = 5000.0
tech.add_via(v)
