Automatic IP (intellectual property) matching is a key to the reuse of IP cores. A new tabled logic programming-based IP matching algorithm is given that can check whether a given programmable IP can be adapted to match a given specification. When such adaptation is possible, the algorithm also generates a device driver (an interface) to adapt the IP. Though simulation, refinement and bisimulation algorithms exist, they cannot be used to check the adaptability of an IP, which is the essence of reuse. The IP matching algorithm is based on a formal verification technique called forced simulation. A forced simulation matching algorithm is implemented using a tabled logic programming environment, which provides distinct advantages for encoding such an algorithm. The tool has been used to match several specifications to programmable IPs, achieving on an average 12 times speedup and 64% reduction in code size in comparison with previously published algorithms.
