A KKT-based circuit partitioning algorithm

Circuit partition is an important part in VLSI design, and it directly impacts on the overall performance of the circuit. This paper presents an algorithm based on the signal delay, named KKTBA. The Karush- Kuhn-Tucker theorem is used to solve the signal delay optimization problem under the FPGA pins and logic capacity constraints and get interconnect relationship among elements under the limitations. Get the new associated matrix by solving the KKT equations, while using the Markov process to obtain the partition results. The experimental results show that the algorithm can guarantee the partition results to meet various constraints, with low complexity of time and space. ©2012 by Binary Information Press.
