In the modern scenario as we go for low-power VLSI design, a useful technique is to design the combinational part of any circuit in a cyclic fashion. Combinational circuits are generally considered as structured acyclics. However, cyclic loops can be introduced in combinational circuits. The main purpose of the cyclic circuit is to introduce structural feedback and avoid logical feedback to obtain the primary combinatorial output. The study of the cyclic circuit includes a functional analysis, ie to determine which values will appear, the time analysis that determines when these values will appear and the area, as a measure of the number of transistors in the final manufacture. The objective of the study is the design and verification of different combinational circuits in the combinational cyclical method optimizing area, power and delay. Detailed study of the circuit model, its functional and temporal behavior, the synthesis of the circuit using the cyclic combinational method, circuit simulation using the standard simulator, the framework of the analysis including area, energy, time consideration are studied in this work.
