Abstract
A block of circuitry contains at least one sub-block. Test patterns for the sub-block (sub-level test patterns) include sub-level test stimuli and corresponding sub-level test responses. These are ported to the block-level to produce block-level test patterns, block-level test stimuli, and block-level test responses. The block-level test patterns are validated as follows. Propagation of the block-level test stimuli through the block-level design is computed. The signals produced by such computed propagation at the sub-block inputs are compared against the sub-level test stimuli, and the signals produced by such computed propagation at the block outputs are compared against the block-level test responses.
