Popis: The article presents a synthesis strategy focused on low power implementations of combinatorial circuits in an array-type FPGA structure. Logic functions are described by means of BDD. A new form of the SWitch activity BDD diagram (SWBDD) is proposed, which enables a function decomposition to minimize the switching activity of circuits. The essence of the proposed idea lies in the proper ordering of the variables and cutting the diagram, ensuring the minimization of switching in the combination circuit. This article contains the results of experiments confirming the effectiveness of the developed concept of decomposition. They were performed on popular benchmarks using academic and commercial synthesis systems.
