What is the source that Ansys is using for the level 54 MOSFET devices?

      I am trying to determine the input impedance to a chain of cascaded CMOS inverters. I have a working simulation using the Nexxim Transient Analysis but when the input clock is low (0 Volts), the impedance I measure by doing V(port1)/I(port1) is -50 ohms. That could potentially be correct, but I have no way to verify it if I don't know how Ansys is actually treating the device. I attached a picture of my circuit.

      HiArray,nPlease go through the BSIM4 MOSFET Model, Level 54 section of the Circuit help document for detailed parameter lists associated with the Level 54 MOSFET.nAll the best.nBest Regards,n
