To effectively test a digital system, one must first define what constitutes a failure. Abramovici, M

ATPG is the software side of the solution. Algorithms like D-Algorithm, PODEM, and FAN are used to mathematically determine the exact sequence of 1s and 0s needed to reveal a specific fault. Modern ATPG tools focus on maximizing "fault coverage"—the percentage of possible faults a test can catch. Design for Testability (DFT) Strategies digital systems testing and testable design solution
