Test Pattern Generator For SCART And RGB TVs

CRTs don’t last forever, and neither do the electronics that drive them. When you have a screen starting to go wonky, then you need a way to troubleshoot which is at fault. A great tool for that is a ...

test pattern

[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 ...

Simulation Mismatches Can Foul Up Test-Pattern Verification

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 ...

Hierarchical test improves pattern application efficiency

For over 15 years, I've been a big proponent of hierarchical test. Hierarchical test is the commonly used term for creating DFT (design-for-test) features and test patterns at lower level circuit ...
