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.

Back when semiconductor devices contained only a few thousand gates, manufacturing test was almost an afterthought. The development team threw the chip “over the wall” to the test engineers, who ...

Handling timing exception paths in ATPG tools while creating at-speed patterns has always been a tough and tricky task. It is well understood that at-speed testing is a requirement for modern ...

System-level test (SLT), once used largely as a stopgap measure to catch issues missed by automated test equipment (ATE), has evolved into a necessary test insertion for high-performance processors, ...

Power management in contemporary system-on-chip (SoC) designs is almost unimaginably complex. Processors and other chip cores turn on and off as needed. Advanced features such as dynamic voltage and ...
