@Tim Edwards Hi, when I perform a parasitic extraction, parasitic capacitors are extracted, but no parasitic resistors are extracted. Am I doing something wrong? The extraction command is as follows:

extract do local
extract all
ext2spice cthresh 0
ext2spice rthresh 0
ext2spice

You need different commands to extract parasitic resistors (rthresh is for something else). See the video or the slides of the Chipalooza Physical Verification workshop.

Thanks! I did not know this great video.
