Xyce
Xyce – Originally developed in support of the electrical designers at Sandia National Laboratories, Xyce has become a large part of the design and analytical process of circuit simulations. As a parallel code, it not only allows the simulations of circuits of unprecedented size, but has addressed possible solutions to critical numerical kernels such as improved time-stepping algorithms and controls, better convergence of the nonlinear solver, and improved device methods.
