A transistor remains permanently non-conductive, converting combinational circuits into sequential networks due to charge storage on output nodes. digital systems testing and testable design solution
By shifting data into the scan chains, an external tester can establish any arbitrary internal state (Controllability). After applying a single functional clock cycle to capture the system's response, the new internal states can be shifted out and verified (Observability). Built-In Self-Test (BIST) digital systems testing and testable design solution
Add scan chains and BIST logic during the synthesis phase of your design. Final Thoughts digital systems testing and testable design solution
