Abstract

Dividing a large-scale design into parts for hardware prototyping and emulation is very important for integrated circuit design flow. In this paper, we present a suite of algorithms to solve the partitioning problem in general field programmable gate arrays (FPGAs) prototyping and hardware emulation. Our k-way hypergraph partitioner is based on a multi-level framework and its performance is similar to the well-known partitioners hMetis (Karypis et al., 1999) and KaHyPar (Akhremtsev et al., 2017). Based on this framework, we take up some algorithms which solve partitioning problems with varying objectives and constraints extracted from logic emulation scenarios. These objectives and constraints take FPGA resources, interconnection resources, flip-flops, and clock domains into account, which are all important factors in FPGA prototyping and hardware emulation. We test our algorithms using ISPD98 benchmarks and several industry cases. The experimental results show that our algorithms are efficient and effective in solving different partitioning problems.
