Abstract
A circuit architecture for testing a programmable logic matrix, e.g., the PLA type, has a group of input latches and a corresponding group of output latches connected to the matrix, and test information paths structured with at least one data bus and one address bus. The input latch and the output latch are connected electrically to the test data bus and to the test address bus to allow matrix testing with considerable time saving over known circuitry.
