Title:
SEMICONDUCTOR INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JP2964799
Kind Code:
B2
Abstract:
PURPOSE: To obtain a scan pass test circuit reduced in erroneous operation in a semiconductor integrated circuit.
CONSTITUTION: A signal is inputted to a plurality of flip-flops 10-1, 10-2, 10-3 used in a scan pass test through selector circuits 9-1,9-2,9-3 so that the clock signals of the flip-flops always become the signals of the clock signals of the flip-flops of the inverted previous stage to increase an operation margin.
