Evaluation of Hierarchical FPGA partitioning methodologies based on architecture Rent Parameter
Résumé
The complexity of circuits to implement on FPGA has necessitated to explore hierarchical interconnect architectures. A large body of work shows that a good partitioning hierarchy, as measured by the associated rent parameter, will correspond to an area-efficient layout. We define the architecture rent parameter of a netlist to be the lowest bound on the rent parameter of any partitioning hierarchy of the netlist. Experimental results show that a combination between a multilevel bottom-up clustering and a top-down refinement generates partitioning hierarchies whose rent parameters are lower than those of other methods.
