HI
You can search on the forum. There are some books about SPICE and PSPICE.
You can also viste this site, It is very nice explain How does SPICE work.
Spice works kind like a programming language. You write a circuit in characters (like numbers an letters) and then the software kind of 'compiles' it to generate the results. The comiling process is more like an analyse process.
I am sorry if I did not sound clear. I know how to use SPICE. What I meant was, I needed the mathematical details behind the working of SPICE, like is it a frequency domain solver or a time domain solver, how are the KCL and KVL matrices obtained etc.
maybe you can ask the makers of this site:http://ngspice.sourceforge.net/faq.html they have made a open-source implementation of SPICE I think they have to know it... Sorry that I can't help you
Hi,
I am also seeking how spice work. i mean the mathematical method that used to analyze the circuit under simulation. such methds used sparse matrix, newton methd. so i have found some sites that can help u understand what are u looking for. **broken link removed**
i also i recommend u to look at in berekely university
