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.
Scan testing has been the foundation of digital-device production test for many years. Several innovations have been developed to keep up with the growth in pattern-set sizes brought about by large ...
Two test strategies are used to test virtually all IC logic—automatic test pattern generation (ATPG) with test pattern compression, and logic built-in self-test (BIST). For many years, there was a ...
Two test strategies are used to test virtually all IC logic: automatic test pattern generation (ATPG) with test pattern compression and logic built-in self-test (BIST). This article will describe how ...
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.
[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...
