Abstract
A semiconductor circuit for testing a logic circuit, the semiconductor circuit including: an exclusive OR circuit receiving an input testing signal to a circuit under testing and a output testing signal from the circuit under testing; a multiplexer receiving a result signal output from the exclusive OR circuit and a clock signal; and a flip-flop storing a logical value represented by a captured signal in synchronization with a multiplexed signal output from the multiplexer, the captured signal being selected from a entered signal (I) and a data signal that is output from another semiconductor circuit for testing.
