The core of the presented algorithm is recursive bipartitioning of a circuit. The bipartitioning procedure consists of three stages: (0) detection of critical paths; (1) bipartitioning of a set of primary inputs and outputs; and (2) bipartitioning of a set of logic-blocks. In (0), the algorithm computes the lower bounds of delays for paths with path delay constraints and detects the critical paths based on the difference between the lower and upper bounds dynamically in every bipartitioning procedure. The delays of the critical paths are reduced with higher priority. In (1), the algorithm attempts to assign the primary inputs and outputs on each critical path to one chip so that the critical path does not cross between chips. Finally in (2), the algorithm not only decreases the number of crossings between chips but also assigns the logic-blocks on each critical path to one chip by exploiting a network flow technique. The algorithm has been implemented and applied to MCNC PARTITIONING 93 benchmark circuits. The experimental results demonstrate that it resolves almost all path delay constraints while maintaining the maximum number of required I\/O blocks per chip small compared with conventional algorithms. <\/jats:p>","DOI":"10.1142\/s0218126697000280","type":"journal-article","created":{"date-parts":[[2003,10,16]],"date-time":"2003-10-16T00:35:19Z","timestamp":1066264519000},"page":"373-393","source":"Crossref","is-referenced-by-count":0,"title":["A Performance-Oriented Circuit Partitioning Algorithm with  Logic-Block Replication for Multi-FPGA Systems"],"prefix":"10.1142","volume":"07","author":[{"given":"Nozomu","family":"Togawa","sequence":"first","affiliation":[{"name":"Department of Electronics, Information and  Communication Engineering, Waseda University, 3-4-1 Okubo,  Shinjuku, Tokyo 169, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masao","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and  Communication Engineering, Waseda University, 3-4-1 Okubo,  Shinjuku, Tokyo 169, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuo","family":"Ohtsuki","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and  Communication Engineering, Waseda University, 3-4-1 Okubo,  Shinjuku, Tokyo 169, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126697000280","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T03:46:24Z","timestamp":1565149584000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126697000280"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,10]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1997,10]]}},"alternative-id":["10.1142\/S0218126697000280"],"URL":"https:\/\/doi.org\/10.1142\/s0218126697000280","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"value":"0218-1266","type":"print"},{"value":"1793-6454","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,10]]}}}
