Partitioning and Restructuring Designs on the Behavioral Level

In this paper a new approach for partitioning designs on the behavioral level is presented. Our main objective is to introduce regularity in order to facilitate resource sharing on a very high level. To accomplish this goal we try to identify similar parts of a specification which can be described by using one function/entity. We present a new metric for similarity, which considers data flow and control flow as well. This is an extension to previously published approaches, which have mostly been restricted to data driven applications. Because we partition the specification of a design prior to high level synthesis, our approach is very efficient and can also be applied to software and hardware/software codesign. The first results are encouraging for further research on this new methodology
