概要

• 論文の詳細を見る

• We have fabricated a LUT-based FPGA device with functionalities measuring within-die variations in a 90nm process. Variations are measured using ring oscillators implemented as a configuration of the FPGA. Random variations are dominant in a 48×48 configurable array laid out in a 3mm×3mm square region. It has a functionality to measure delays on actual signal paths between flip flops by providing two clock pulses. Measured variations are used to maximize the operating frequency of each device by choosing the optimal paths. Optimizations of routing paths using a simple model circuit reveals that performance of the circuit is enhanced by 2.88% in average and a maximum of 9.34%.
