COMBINATORY LOGIC CIRCUIT TESTING DEVICE AND INTEGRATED CIRCUIT COMPRISING SUCH A DEVICE.

摘要

P This device for testing a combinational logic circuit 4, comprises on the one hand a test sequence generator circuit 30 for applying to N inputs of the combinational logic circuit test logic signals and on the other hand a output 5 to analyze the output signals of the combinational logic circuit, these test sequences consisting in successively applying to each of the N inputs E1, E2, E3 and E4 an alternating sequence, at least twice, of "1" and "O "logic while to the other inputs is applied a word of N-1 binary elements to ensure the transmission of said alternating sequence to the output of the combinational logic circuit. BR/ Application: testing of logic circuits. BR/ (CF DRAWING IN BOPI) BR/ BR/ /P
