WebScan chain operation involves three stages: Scan-in, Scan-capture and Scan-out. Scan-in involves shifting in and loading all the flip-flops with an input vector. During scan-in, the data flows from the output of one flop to the scan-input of the next flop not unlike a shift register. WebScan Design Circuit is designed using pre-specified design rules. Test structure (hardware) is added to the verified design: Add a test control(TC) primary input. Replace flip-flops by …
