AnySyn: A Cost-Generic Logic Synthesis Framework with Customizable Cost Functions

Abstract: Modern technology-independent logic synthesis has been developed to optimize for the size and depth of AND-Inverter Graphs (AIGs) as a proxy of CMOS circuit area and delay. However, for non-CMOS-based emerging technologies, AIG size and depth may not be good cost estimations. Dedicated algorithms optimizing for more complex cost functions have been proven effective for their specific target applications yet require time and experts in both logic synthesis and the targeted technology to develop. In this work, we propose AnySyn, a cost-generic optimization framework for agile experimentation and prototyping of various customized cost functions before investing in developing specialized algorithms. Experimental results show that AnySyn outperforms non-specialized size and depth optimization algorithms by 14% and 19% on average and achieves comparable results to specialized algorithms within acceptable CPU time.
