Abstract:
A method of processing a scan test data sequence for testing a circuit device, comprising the acts of:separating the scan test data sequence into at least two scan streams, wherein each scan stream includes a sequence of scan data segments; and for each scan stream: storing the scan data segments non-contiguously in a memory; providing processing infornmation associated with each scan data segment; testing the circuit device by applying thereto the sequence of scan data segments; providing a pointer to each scan data segment in the processing infornmation associated with the scan data segment; separating the scan test data sequence into at least a scan-in stream and a scan-out stream, the scan-in stream including a sequence of scan-in data segments. and the scan-out stream including a sequence of scan-out data segments; for each scan data segment, calculating at least one processing delay value; and interleaving the scan data segments in accordance with the at least one processing delay value of each scan data segment.
