Partial BIST with recording of the connections between individual blocks

摘要

A component with integrated circuits combined into functional blocks, in which case the functional blocks have connections between them and a relevant residual logic. The residual logic of the functional blocks is first tested by entering test data into the residual logic and a first signature is output for each block, and then the connections between the blocks are tested by transferring test data via the connections and a second signature is output.
