Aiming for 99% or higher for stuck-at faults.

The traditional method of "testing from the outside in" is obsolete.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.

The ability to not just say a chip is "bad," but to identify exactly where the failure occurred to improve future manufacturing yields. Conclusion

The ability to determine the signal value at any internal node by looking at the output pins. Key DFT Techniques for High-Quality Results

Without a robust testing strategy, defective chips reach the consumer, leading to: Brand damage.

The ability to establish a specific logic value at any internal node.

Building a high-quality digital system requires a symbiotic relationship between design and test. By integrating advanced DFT structures and leveraging sophisticated ATPG tools, companies can ensure that their silicon is not only innovative but also reliable and cost-effective. In a world where failure is expensive, testable design is the ultimate insurance policy.

A high-quality testing flow relies heavily on . ATPG software analyzes the netlist and automatically creates the mathematical patterns needed to achieve maximum fault coverage. A "high-quality" solution in this context means:
