On channel segmentation design for row-based FPGAs

The channel segmentation design problem for row-based field-programmable gate arrays (FPGAs) is to design a segmented channel to maximize the probability of successful routing. An algorithm which takes an arbitrary net distribution and an integer K (specifying the maximum number of segments allowed in routing a net) as inputs, and automatically generates a segmented channel which is most suitable for K-segment channel routing is presented. The algorithm was tested extensively over various net distributions. An algorithm for segmented channel routing based on reducing the problem to the maximum independent set problem for undirected graphs is also presented.<>
