ABSTRACT:
Circuit responses to a stimulus may be compacted, decreasing the number of pin outs, without increasing the circuit element length, using a compactor. In accordance with one embodiment of the present invention, errors may be detected in scan chains used for integrated circuit testing. The number of outputs applied to output pins or other connectors may be substantially decreased, resulting in cost savings.
