Module Selection and Scheduling using Unrestricted Libraries

Most high–level synthesis schedulers are only capable of mapping an operation to one specific module type. To ensure a full design space exploration, a synthesis system should however select freely from a library containing modules with a large variety in delay, area and so on. A novel module selection and scheduling approach is presented, which allows the full use of such unrestricted libraries. Extensive benchmark results show very fast running times and optimal solutions. Hence this approach clearly illustrates the advantages of synthesis tools which can fully cope with unrestricted libraries, as they lead to designs with less module area.
