Does ASITIC model skin effect?

0

Yes, ASITIC models skin effect with the pix and indmat commands or through the various 2-port commands such as 2px. By sub-dividing segments in width/thickness and generating the partial inductance matrix, during the order reduction of the matrix, a complex frequency dependent “inductance” matrix results. The real part of this matrix increases as a function of frequency as it models skin and proximity effects. For the simple pi command, the resistance is calculated at DC and then a closed-form expression is used to estimate the skin effect in the conductor at high frequency. This neglects proximity effects, though.
