Abstract

The quality of at-speed testing is being severely challenged by the problem that an inter-clock logic block existing between two synchronous clocks is not efficiently tested or totally ignored due to complex test control. This paper addresses the problem with a novel inter-clock at-speed test control scheme, featuring a compact and robust on-chip inter-clock enable generator design. The new scheme can generate inter-clock at-speed test clocks from PLLs, and is feasible for both ATE-based scan testing and logic BIST. Successful applications to industrial circuits have proven its effectiveness in improving the quality of at-speed testing.
