This paper presents the algorithms for CMVSIM, a program for performing the transient simulation of grid based analog signal processors on a massively parallel computer. A grid-based equation formulation approach and a block-diagonal preconditioned CGS algorithm are described, and it is shown how they are used to efficiently perform transient simulation using the massively parallel Connection Machine. Experimental results using CMVSIM to simulate realistic image processing circuits are given to demonstrate that the algorithms presented are effective for a general class of grid-based signal processors. In particular, the results presented demonstrate that CMVSIM: running on a full-size Connection Machine can be as much as 650 times faster than what is, to the authors' knowledge, the fastest serial transient simulation algorithm running on a SUN-4/490 workstation
