Hai all,

       My name is anil. I am new to this group.

Hope someone can help me regarding the spice3f4


I am trying to know how the netlist is converted into datastructure

First of all, after writing a netlist , it convert into a circuit then it convert into matrix before doing nodal analysis [I] = [G][V]

It uses the matrix such incident matrix or adjancy matrix etc..

I want to know exactly which matrix type does it uses. If anyone had alreadylook the code, then they may know it.

I want to know how the spice does?

If anyone have idea or documentation regarding the inside   spice , plz let me know

Hope someone can help me

Thank you

Regards,
anil

Sorry the best doc is the source code, but the general method is described in the book

Inside Spice

and the detailed matrix derivation in

Computer-Aided Analsysis of electronic circuits: algorithms & computational techniques; Leon O. Chua & Pen-Min Lin

29 years old but still a reference for starting. Later improvements of implementation techniques are very are found in books.
