This project involves the development of a program to read a sparse matrix from an MM file, convert it to Compressed Sparse Row (CSR) format, and then solve for vector x using Jacobi's method.

Abstract: The sparse matrix solver has become a bottleneck in simulation program with integrated circuit emphasis (SPICE)-like circuit simulators. It is difficult to parallelize the solver because of ...

Abstract: We implement mixed precision sparse matrix solver in the transient simulation of analog circuits. In each time step, we need to perform one single precision LU factorization and a few steps ...

The underlying solver algorithms used in power grid (PG) simulation today are derivations of circuit simulation algorithms first developed many decades ago. In fact, the 40 th anniversary of SPICE (a ...

High-frequency electromagnetic simulation has evolved from “wow, now I can see how electromagnetic fields behave” to needing to know how various EM fields interact in large, complex systems. During ...
