Abstract :
In this paper, we consider the problem of configuring Field Programmable Gate Arrays (FPGA´s) so that some given function is computed by the device. Obtaining the information necessary to configure a FPGA entails both logic synthesis and logic embedding. Due to the very constrained nature of the embedding process, this problem differs from traditional multilevel logic synthesis in that the structure (or lack thereof) of the synthesized logic is much more important. Furthermore, a metric-like literal count is much less important. We present a communication complexity-based decomposition technique that appears to be more suitable for FPGA synthesis than other multilevel logic synthesis methods. The key is that our logic optimization technique based on reducing communication complexity is good enough to allow a simple technology mapping to work well for FPGA devices
