BSPDN-Elite: A Comprehensive Framework for Optimizing Timing, Power and Routing Resources in BSPDN Designs
DescriptionBackside power delivery networks (BSPDN) provide superior power integrity while freeing backside routing resources. However, existing works fail to fully exploit these resources for power, performance, and area (PPA) optimization through strategic net allocation. This paper presents a co-optimization framework that maximizes PPA by strategically routing both clock and signal nets on the backside, enabling double-side routing. Experimental results demonstrate 88.1% IR-drop reduction, 23.0% frequency improvement, 10.9% power savings, and timing improvements (66.3% WNS, 40.2% TNS) over FSPDN with negligible nTSVs overhead.
