Wrapper design for multifrequency IP cores.

Wrapper design for multifrequency IP cores.

This paper addresses the testability problems raised by intellectual property cores with multiple clock domains. The proposed solution is based on a novel core wrapper architecture and a new wrapper design algorithm. It is shown how multifrequency at-speed test response capture can be achieved via t...
