The traditional method of "testing from the outside in" is obsolete. Modern chips are too dense for external testers to probe every internal node. This is where comes in.
ATPG is the algorithmic heart of digital testing. Given a gate-level netlist and a fault list, ATPG generates input vectors to excite and propagate faults to observable outputs. The traditional method of "testing from the outside
In the semiconductor industry, quality is non-negotiable. A robust solution in digital systems testing and testable design is no longer an optional add-on but a fundamental requirement for product success. By integrating , BIST , and ATPG methodologies into the design flow, engineers can create systems that are not only functionally superior but also verifiable, reliable, and cost-effective to manufacture. and cost-effective to manufacture.
