Formal Verification of Approximate Sequential Circuits,ormal property checking (e.g., specification of a liveness property). On the contrary, our approach is fully automated. Furthermore, the case studies provided later in this chapter show that the error analysis of the approximate sequential circuits can lead to a different conclusion altogether, when

However, approximate computing can also improve the efficiency of a circuit in terms of speed and area by relaxing the constraints on computational accuracy. Hence, an approximation synthesis tool is able to provide much better optimization compared to a conventional synthesis tool si

Conclusions and Outlook,its. Our methodologies are efficient, scalable and significantly advance the current state-of-the-art of the approximate hardware design. We have addressed the important facets of approximate computing—from formal verification and error guarantees to synthesis and test of approximation systems.
