hi all, I am now using hspice to do a simulation for my circuit, and i want to define the input signal.I know something like this: vp 1 0 pwl (0 1 10n 0.5v) will work, but my input signal lasts a long time(which can be described as a vector in matlab workspace), so it is impossible to write it...
I am now optimizing my circuit using both matlab and hspice. I have two questions :1. how to import a varible in matlab workspace to hspice as its input source? 2. how to obtain a time variant resistance in hspice 3. how to control the value of this resistance, by matlab optimizing function...
