In this work, we evaluate bi-directional and unidirectional FPGA routing architectures in terms of energy and power consumption using an updated power estimation framework compatible with VPR 5.0. The goal of this research is to help FPGA vendors find the best FPGA architectures. Initially, we make some general observations on how two types of routing architectures affect speed, area consumption, and power consumption. We observe how routing buffer sizing affects both the critical path delay and power and energy consumption of FPGAs with certain routing architectures. Our results show that uni-directional routing architecture, in all but one case, is the most energy efficient choice both in the traditional FPGA domain and the mobile domain where clock frequencies are fixed.
