Adds silicon area near arrays; introduces minor timing delays. Board-level interconnect and pin testing via JTAG.
In the modern era, digital systems are the silent arbiters of our daily lives. From the microprocessor in a pacemaker to the flight control unit of an airliner, from the 5G modem in a smartphone to the cryptographic engine in a banking server, digital logic is ubiquitous. However, there is a hidden reality behind every "power on" success: the rigorous, often invisible discipline of . digital systems testing and testable design solution
Standard flip-flops are replaced with "Scan Flip-Flops" that feature an internal multiplexer (MUX). Adds silicon area near arrays; introduces minor timing
What are your primary ? (e.g., high fault coverage targets, strict silicon area overhead budgets) Adds silicon area near arrays
Placed between the core logic and each physical I/O pad.
