Technology mapping of multi-output function into LUT-based FPGA

Abstract

The paper presents the essence of technology mapping of multi-output functions in modern logic blocks of FPGA circuits. Impressive configurable abilities of the blocks enable to lead decomposition in a way to use available logic resources of LUT-based FPGAs. As modern configurable logic blocks include several LUT blocks, it is necessary to search for such a decomposition model that would enable technology mapping simultaneously in LUT blocks and in whole configurable logic blocks. In the paper, the authors present a series of experiments and prove the effectiveness of multiple decomposition and presented methods.
