Hi, The following code is a hspice code. what are the exact formulas for calculating the matrice elements Lo, Co, Ro, Go, Rs, Gd? In other words, I want Lo, Co, Ro, Go, Rs, and Gd calculation formulas. thank you.
The following input netlist file shows RLGC input for the W Element:

Lo: DC inductance matrix, per unit length [H/m].
Co: DC capacitance matrix, per unit length [F/m].
Ro: DC resistance matrix, per unit length [Ω/m].
Go: DC shunt conductance matrix, per unit length [S/m].
Rs: Skin effect resistance matrix, per unit length [Ω/m√Hz].
Gd: Dielectric loss conductance matrix, per unit length [S/m.Hz].
