[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 ...

Test patterns play critical roles in physical layer compliance testing by challenging different aspects of a system. Receivers in HSS (high-speed serial) technology must be stable. When the average ...

Design for testability (DFT) works to make a circuit more testable to ensure that it was manufactured correctly. Alfred Crouch explains the purpose of DFT in his book, Design-For-Test for Digital ICs ...

Because I work for a provider of test tools that enable andproduce production test patterns, I am often asked what the best patterns areto use for production test. The answer depends on the device ...

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.
