Exploiting Isomorphism for Speeding-Up Instance-Binding in an Integrated Scheduling, Allocation and Assignment Approach to Architectural Synthesis

Abstract

Register-Transfer (RT-) level netlists are said to be isomorphic if they can be made identical by relabeling RT-components. RT-netlists can be generated by architectural synthesis. In order to consider just the essential design decisions, architectural synthesis should consider only a single representative of sets of isomorphic netlists. In this paper, we are using netlist isomorphism for the very first time in architectural synthesis. Furthermore, we describe how an integer-programming (IP-) based synthesis technique can be extended to take advantage of netlist isomorphism.
