A Functional-Logic Library for Wired

We develop a Haskell library for functional-logic programming, motivated by the implementation of Wired, a relational embedded domain-specific language for describing and analysing digital circuits at the VLSI-layout level. Compared to a previous library for logic programming by Claessen and Ljungl\uf6f, we support residuation, easier creation of logical data types, and pattern matching. We discuss other applications of our library, including test-data generation, and various extensions, including lazy narrowing
