Interpolating functions from large Boolean relations

Abstract

Boolean relations are an important tool in system synthesis and verification to characterize solutions to a set of Boolean constraints. For physical realization as hardware, a deterministic function often has to be extracted from a relation. Prior methods however are unlikely to handle large problem instances. From the scalability standpoint this paper demonstrates how interpolation can be exploited to extend determinization capacity. A comparative study is performed on several proposed computation techniques. Experimental results show that Boolean relations with thousands of variables can be effectively determinized and the extracted functional implementations are of reasonable quality.
