Abstract:
1. A computer-implemented method for simulating operation of an integrated circuit, the method comprising: using a parallel processing system, generating a system of differential or algebraic equations (DAE) modeling operation of the integrated circuit; discretizing the system of DAE to form a discretized DAE; partitioning the integrated circuit into load balanced partitions, each partition representing a subsystem of the integrated circuit; for each partition representing a subsystem of the integrated circuit: when the DAE are nonlinear, linearizing the discretized DAE using a nonlinear iterative method to obtain a linear system having a circuit Jacobian matrix; solving the linear system using a linearized circuit Jacobian matrix solver, wherein the solving comprises: recursively performing the steps from partitioning the circuit till obtaining a solution to I+M
