Abstract

A general description of an enhanced scheme fordesigning completely self-testable MCMs is given. Itallows performance testing and diagnosis of MCMinterconnections for dynamic effects. This scheme isbased on embedding of cascadable test pattern generatorsand reconfigurable signature analyzers into thedesign of MCM dies. A theory of partitioning of linearregisters is applied to devise a two phase distributeddiagnosis strategy. The design of a novel MISR reconfigurationscheme that enables high diagnosis resolution,is presented. Simulation results obtained confirm theeffectiveness of our BIST technique.
