Scan insertion是什么

http://www.accentsjournals.org/PaperDirectory/Journal/IJACR/2014/6/43.pdf WebMar 8, 2024 · When software professionals want to enable a scan test for a chip design, they can insert additional test logic, called scan insertion. Scan insertion primarily comprises two steps. The first is to replace the plain memory cells, like flip-flops or latches, using the scan cells. The second step is to connect these cells to form one or more chains.
