Pipelining combinational circuits

For a multilevel combinatorial circuit, the problem of increasing its performance is considered. The problem is to divide the circuit into a given number of cascades and to connect them via registers providing pipeline-wise development of incoming signals. The frequency of incoming signals is established in the process of dividing the circuit. This frequency must be as high as possible. To solve this problem a model based on the representation of the circuit in the form of a directed graph is used.
