Abstract

This paper presents a performance-oriented placement and routing tool for field-programmable gate arrays. Using recursive geometric partitioning for simultaneous placement and global routing, and a graph-based strategy for detailed routing, our tool optimizes source-sink pathlengths, channel width and total wirelength. Our results compare favorably with other FPGA layout tools, as measured by the maximum channel width required to place and route several benchmarks.
