Digital Systems Testing And Testable Design Solution High Quality Upd May 2026

Introduction: The Hidden Crisis in Modern Electronics In the age of 5G, autonomous vehicles, and edge AI, the complexity of digital systems has exploded. A single System-on-Chip (SoC) today contains billions of transistors. While the design community focuses heavily on performance, power, and area (PPA), a silent crisis looms: the gap between design complexity and our ability to test it.

For a product to be "high quality," it is insufficient to simulate perfectly. Real-world silicon contains physical defects—bridging faults, stuck-at faults, timing anomalies, and process variations. Without a rigorous strategy and a testable design solution , defect levels (measured in DPPM—Defective Parts Per Million) will skyrocket. Introduction: The Hidden Crisis in Modern Electronics In
