Abstract

An interconnect test and diagnostic scheme based on distributed BIST resources in SOC and MCM designs is described. Test and diagnosis is enabled by embedding cascaded test pattern generators and reconfigurable signature analyzers into the design. The theory of partitioning of linear registers is applied to devise a two phase distributed diagnosis strategy. The design of a novel MISR reconfiguration scheme that enables high diagnosis resolution is presented.
