Architectural Analysis of FPGA Technology Impact
share
The use of high-level languages for designing hardware is gaining popularity since they increase design productivity by providing higher abstractions. However, one drawback of such abstraction level has been the difficulty of relating the low-level implementation problems back to the original high-level design, which is paramount for architectural optimization. In this work (developed between April 2013 and April 2014), we propose a methodology to analyze the effects of technology over the architecture, and to generate architectural-level area, delay and power metrics. Such feedback allows the designer to quickly gauge the impact of architectural decisions on the quality of generated hardware and opens the door to automatic architectural analysis. We demonstrate the use of our technique on three FPGA platforms using two designs: a Reed-Solomon error correction decoder and a 32-bit pipelined processor implementation.
