Hi all, These are my first questions on circuit simulations techniques. Circuit simulators like spice use Modified Nodal Analisys (MNA) to solve linear and linearized circuits. The solution process consists mainly in the solution of a linear system Ax=B. There are "direct" methods and "iterative" ones. What are the differences between the two and what are the peculiarities and drawbacks ? Are there alternative solutions to the tho classes of methods stated above ? Thanks, Paolo
