Boolean Satisfiability

This chapter provides the background on Boolean Satisfiability (SAT) necessary for the description, in the next chapter, of an ATPG engine based on SAT. The main concepts of SAT solvers are reviewed in Section 3.1. An overview of advanced SAT techniques is given in Section 3.2. In Section 3.3, the standard transformation of a given circuit into constraints for a SAT solver is introduced. Finally, Section 3.4 provides a short overview of circuit-oriented SAT techniques.
