To Dear all: Is it Ok to use negative RLCG values in Spice simulation for time domain and frequency domain simulation if I happen to have those negative circuit element values? Passivity is one possible reason that people say no that I can think of. I cannot find definite answer not using negative values. Anyway Pspice allows me to use those values, I think there is a reason for it.
