-* HP Memristor SPICE Model
-* For Transient Analysis only
-* created by Zdenek and Dalibor Biolek
-**************************
-* Ron, Roff - Resistance in ON / OFF States
-* Rinit - Resistance at T=0
-* D - Width of the thin film
-* uv - Migration coefficient
-* p - Parameter of the WINDOW-function
-* for modeling nonlinear boundary conditions
-* x - W/D Ratio, W is the actual width
-* of the doped area (from 0 to D)
