US Patent 4,845,633 (22), July 1989.
Abstract: A system for programming a reprogrammable, asynchronous logic cell to perform virtually any logic operation, particularly those characterized as a class of petri nets, is presented. Programming is achieved by setting the states of the switches in each cell. The system allows avoidance and bypass of defective cells.
Keywords: programming, graphically; programmable asynchronous logic cell; programmable array; avoidance (and) bypass (of) defective cell.
