FPGA-based Heterogeneous Solver for Three-Dimensional Routing

A heuristic algorithm is one of the approaches to solve an NP-hard problem. In order to enhance the capability of the system, heterogeneous computing is often adapted. In this paper, we propose an FPGA-based heterogeneous solver for three-dimensional routing. The proposed system is implemented into multiple FPGA boards and a single-board computer. The experimental results demonstrate that the proposed system outperforms a single FPGA system.
