In this paper we evaluate a new multilevel hierarchical MFPGA. The specific architecture includes two unidirectional programmable networks. A downward network based on the butterfly-fat-tree topology, and a special rising network. New tools are developed to place and route several benchmark circuits on this architecture. Comparison with the traditional symmetric, Manhattan mesh architecture shows that MFPGA can implement circuits with fewer switches and a smaller area.
