Digital Systems Testing And Testable Design Solution High Quality Jun 2026

Miron Abramovici, Melvin A. Breuer, and Arthur D. Friedman

Understanding high-quality testing requires distinguishing between three critical concepts: Miron Abramovici, Melvin A

High-quality digital design starts with the premise that a system must be controllable (easy to set to a specific state) and observable (easy to see internal signals). Integrated Design Cycles: Melvin A. Breuer

Modern SoCs (Systems-on-Chip) contain billions of logic gates, making it impossible to check every possible state combination. Miron Abramovici, Melvin A

Secure test solutions address these concerns through various techniques. Test interface locking requires authentication before test mode activation. Scan chain encryption prevents observation of sensitive data. Partial scan omits security-critical flip-flops from scan chains. Test mode removal permanently disables test interfaces after manufacturing testing completes.
