Abstract
A test system for simultaneously testing a plurality of logic circuits first sets them all to an initial state before beginning testing. The faulty logic circuits which cannot be set to the initial state can be identified, and the testing of the others can proceed, even after only one cycle of attempting to initialize all the logic circuits. If all the logic circuits are faulty, the further testing can be prevented.
