In this article, we present a high-level design tool to support the process of mapping an application onto a FPGA device with dual supply voltages. Our main contribution in this paper is an algorithm, which creates voltage scaling ready clusters by utilizing the timing slack available in the designs. We propose to first create clusters of CLBs within a given CLB-level netlist. This clustering algorithm intends to group chains of CLBs possessing similar amounts of timing slack along their critical path together. Once these clusters are identified, they are placed onto respective V\n            <jats:sub>dd<\/jats:sub>\n            partitions on the device. We have evaluated different dual V\n            <jats:sub>dd<\/jats:sub>\n            fabrics and the potential gain in power consumption is explored. When a subset of the logic blocks on the device can be driven by low V\n            <jats:sub>dd<\/jats:sub>\n            levels (either with a dedicated low V\n            <jats:sub>dd<\/jats:sub>\n            supply or with a programmable selection between low and high V\n            <jats:sub>dd<\/jats:sub>\n            levels for these blocks) this affects placement and routing. As a result the maximum frequency of the designs may be affected. In order to evaluate the overall impact of creating voltage islands, we measured the Energy-Delay Product for our benchmark designs. We observed that the Energy-Delay product can be decreased by 26.9% when the placement of the designs into different voltage levels is guided by our clustering algorithm.\n          <\/jats:p>","DOI":"10.1145\/1391962.1391965","type":"journal-article","created":{"date-parts":[[2008,10,7]],"date-time":"2008-10-07T12:48:29Z","timestamp":1223383709000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["A high-level clustering algorithm targeting dual V\n            <sub>dd<\/sub>\n            FPGAs"],"prefix":"10.1145","volume":"13","author":[{"given":"Rajarshi","family":"Mukherjee","sequence":"first","affiliation":[{"name":"Synopsys, Inc., Mountain View, CA"}]},{"given":"Song","family":"Liu","sequence":"additional","affiliation":[{"name":"Northwestern University, Evanston, IL"}]},{"given":"Seda Ogrenci","family":"Memik","sequence":"additional","affiliation":[{"name":"Northwestern University, Evanston, IL"}]},{"given":"Somsubhra","family":"Mondal","sequence":"additional","affiliation":[{"name":"Neokast Inc., Evanston, IL"}]}],"member":"320","published-online":{"date-parts":[[2008,10,3]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/4.726544"},{"key":"e_1_2_1_2_1","doi-asserted-by":"crossref","unstructured":"Betz V.
