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 ...

Testing digital designs usually requires one or more digital signals, some of which can be very difficult to generate. Pattern generators are specifically designed to address this problem. Whatever ...

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 ...
