Automatic test-pattern generation (ATPG) has played a key role in semiconductor logic test, but several trends driving the need for semiconductor test quality are challenging traditional ATPG tools.

The old adage “time is money” is highly applicable to the production testing of semiconductor devices. Every second that a wafer or chip is under test means that the next part cannot yet be tested.

As chips get ever bigger and more complex, the electronic design automation (EDA) industry must innovate constantly to keep up. Engineers expect every new generation of silicon to be modeled, ...

Design-for-test, or DFT, should facilitate high-quality test, not change the design. Test techniques and strategies need to supply a high-quality test that screens out defective devices, avoiding ...
