Nonlinear equation solvers in SPICE simulators

We have an assignment at the Parallel processing class, the target is to implement a Non-linear Equations solver on cuda based on Newton Raphson method and to interface this solver with an application that deals with nonlinear set of equations. We…

Is the pulse voltage MNA matrix stamp the same as a normal DC voltage?

I am currently doing research on circuit simulators and trying to understand their techniques for simulating specific components. Now, I am at the state of trying to do transient simulation using Jacobian, Newton-Raphson and Backward-Euler methods.…
