Abstract
A pipeline circuit with a test circuit in small circuit scale includes a pipeline circuit including a plurality of groups of flipflops arranged in series and a plurality of combinational circuits respectively arranged between the plurality of groups of flipflops and each having an input connected to an output of a group of flipflops at a previous stage and an output connected to a group of flipflops at a subsequent stage. The plurality of groups of flipflops include groups of flipflops subjected to scan conversion and groups of flipflops not subjected to scan conversion. The pipeline circuit, with a test circuit also includes a scan chain interconnecting the groups of flipflops subjected to scan conversion. An automatic test pattern generating method for testing the pipeline circuit with a test circuit, is also claimed.
