An efficient inter-fpga routing exploration environment for multi-fpga systems

Farooq, Umer, Baig, Imran and Alzahrani, Bander A (2018) An efficient inter-fpga routing exploration environment for multi-fpga systems. IEEE Access, 6. pp. 56301-56310. ISSN 2169-3536

Field programmable gate arrays (FPGAs) have seen a huge evolution since their inception almost three decades ago. Multi-FPGA boards continuously receive an increasing attention by the research community as efficient solutions for complex system prototyping. This is due to reliable high-speed, low-cost, and real-life exploration environment they offer. Although multi-FPGA platforms offer better frequency compared to other prototyping alternatives, expanding logic resource to I/O ratio in FPGAs is causing an increase in time multiplexing ratio of inter-FPGA signals (logical signals) to inter-FPGA tracks (physical resources), which causes a decline in overall system frequency. This paper introduces a generic testing platform for multi-FPGA modeling. With this platform, users will be able to experience overall prototyping cycle of a digital system. The cycle will start from benchmark generation and will go all the way to interFPGA routing. Using generic tools of this platform, we explore the effect of three different inter-FPGA routing approaches on the frequency of final prototyped design. Each routing approach is applied on generic as well as custom multi-FPGA boards. Results obtained through experimentation show that, for generic FPGA board, routing approach better exploiting two- and multi-point tracks of target FPGA board gives better average frequency results as compared to other two routing approaches.
