反应scan chain中scan cell的reorder。在物理实现之前,一个random的scan order被design使用。 在进行physical implementation时,scan order可以使用intra_scan_chain reordering(scan cell只在该scan chain内进行reorder)和inter_scan_chain reordering(
Due to lock-up latch on scan path, tool is not able to improve the chain length by reordering in an efficient manner. Whenever there is a lock-up latch in the chain, the scan chain is broken into two smaller segments. These segments in turn have their own start-end points which are ...
1.A computer program product for implementing a scan chain to test a semiconductor, the computer program product comprising:a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program inst...
1.A method for reducing switching activity during a test scan operation of at least one scan chain in an integrated circuit (IC) comprising the steps of:a) determining stimulus and result value probabilities for a plurality of memory elements in said IC; andb) connecting said memory elements ...
