✦ Synopsis

Logic simulators were originally developed for logic diagram verification. Their use for mask verification is a complex task of logic diagram recognition based on the information gained from masks to be made. The simulator LOMACH is based on the idea that logic states do not propagate through the nodes of a logic diagram but rather through diffusion regions defined directly by the masks. This paper provides postulates governing the logic state wave propagation, and suggests an internal database and algorithms for checking topological correctness and logic function simulation.
