<p>A testability strategy for a complex VLSI device that is implemented in the Piramid digital-signal-processor silicon compiler is presented. The macro test method proposed supports built-in self-test, scan test, restricted partial scan, and test-control logic at various levels in the design hierarchy. The strategy uses techniques such as a macro test plan, transfer information, and intermediate vector storage. The overhead from adding testability is only 10% of the total area and test-program generation is done with 100% fault coverage in a very short time, since there is no need for global test-pattern generation. A set of tools that guide the testability implementation from design to the final test program is described.</p>
