Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...

Test compression sounds like magic. Read on to learn how this trick is done. Large, complex ICs are viable because their design meets test as well as functional requirements. Design for test (DFT) was ...

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 ...
