The ever-increasing density of ASICs, the whole-sale switch to surfacemount technology, and the growing interest in multi-chip modules (MCM), have resulted in testable designs becoming a greater priority. Thus far, designers have considered testability as an issue which comes into play at the very end of the design cycle. However, in the ASIC design flow based on synthesis, it is essential that designers develop a test strategy and address testability issues concurrently with other activities in the design cycle. In this chapter, Test Synthesis and Automatic Test Pattern Generation (ATPG) using the Synopsys Test Compiler (referred to as TC, for short), are discussed.
