Spice to cadence translation - Define vccs in cadence

* 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) 
*
