For CAD tools, this situation increases the difficulty of successfully mapping a circuit into the low-cost FPGAs. Instead of switching to resource-rich FPGAs, the designers could employ depopulation-based clustering techniques which underuse CLBs, hence improve routability by spreading the logic over the architecture. However, all depopulation-based clustering algorithms to this date increase critical path delay. In this paper, we present a timing-driven nonuniform depopulation-based clustering technique, T-NDPack, that targets critical path delay and channel width constraints simultaneously. T-NDPack adjusts the CLB capacity based on the criticality of the Basic Logic Element (BLE). Results show that T-NDPack reduces minimum channel width by 11.07% while increasing the number of CLBs by 13.28% compared to T-VPack. More importantly, T-NDPack decreases critical path delay by 2.89%.<\/jats:p>","DOI":"10.1155\/2010\/158602","type":"journal-article","created":{"date-parts":[[2010,2,17]],"date-time":"2010-02-17T08:30:47Z","timestamp":1266395447000},"page":"1-11","source":"Crossref","is-referenced-by-count":12,"title":["Timing-Driven Nonuniform Depopulation-Based Clustering"],"prefix":"10.1155","volume":"2010","author":[{"given":"Hanyu","family":"Liu","sequence":"first","affiliation":[{"name":"Department of ECE, University of Arizona, 1230 E.
