Digital Systems Testing And Testable Design — Solution High Quality [extra Quality]

: After executing a single clock cycle in normal mode, the resulting internal states are captured back into the scan chains and shifted out to external automatic test equipment (ATE) for evaluation. 2. Built-In Self-Test (BIST)

: As VLSI circuits increase in gate density, the ratio of logic to accessible pins drops, making external probing impossible. 4. Design for Testability (DFT) Strategies : After executing a single clock cycle in

Engineers write clean hardware description code (Verilog/VHDL) while following structural rules, such as avoiding uncontrollable internal clocks, asynchronous resets, and tri-state bus contentions. such as avoiding uncontrollable internal clocks
