Abstract :
This paper presents a method for accelerating analog simulation by incrementally updating the admittance matrix, and re-solving only the part of the matrix that depends on the factors that changed. There is substantial speedup for large linear subcircuits of the type generated by RLGC extractors for interconnect analysis. It makes little if any difference for small nonlinear circuits
