However, Fastcap is not givig right results for extracted capacitances. I have used converthenry to convert fasthenry files to fast cap with following command. converthenry -nRFtrace1.inp -lRFtrace1 -gRFtrace1 -c1.0 -e0-1 -d400 -f I also tried to change discretization step to other values than 400 but results are still wrong and come different for different discretization steps. I get the follow results for 400 discretization step.
