| Abstract(in English) | Look-up table (LUT) has many SRAM and multiplexers, and you can implement any logic function to LUTs if the number of its input signals do not exceed the number of input ports. In other words, it may safely be said that LUT is the perfect logic cell which have ability to represent any logics. But, there might be the logic cell which are fewer than the number of both SRAMs and transistors of LUT. In this paper, we investigate the usage of logic functions by analyzing several benchmarks in order to develop an efficient logic cells. We consider the point that belong to P-equivalence class if permuting some of the input variables of function g1 derives function g2 from g1. As a result, the number of logic functions in P-equivalence class is decreased about 60% compared with all used logic functions. |
