@User: Zero for C (

ext2spice cthresh 0

) is sensible; note that

ext2spice rthresh

is not what you want, as it is for "lumped resistance" used by IRSIM and nothing else that I'm aware of. There is a

tolerance

passed to the

extresist

command. I have not really experimented with the tolerance; the example tutorial usage has a value of 10 which seems to produce sane results.

Ok, thanks for the info. @Tim Edwards
