LYNX: CAD FOR FPGA-BASED NETWORKS-ON-CHIP

We present a computer-aided design (CAD) tool that automatically connects an FPGA application using an embedded network-on-chip (NoC). After discussing the CAD flow steps, we delve into the details of implementing transaction communication using our CAD tool. This request-reply type of communication requires special consideration on FPGAs, for example: low round-trip latency, fair arbitration and correct ordering. We show how to implement transaction communication using embedded NoCs, and show that we can improve latency, throughput and efficiency compared to soft buses generated by a commercial CAD tool.
