Abstract

The integration of a large number of transistors and device scaling results in the development of high-power density within Very Large-Scale Integrated (VLSI) circuits. Power density is directly proportional to chip temperature and grows exponentially as package density increases. As a result, considering temperature impacts at all levels of the VLSI design cycle becomes a fundamental phenomenon because it reduces a circuit’s performance and dependability. To decrease the power density of the circuit, a bi-partitioning heuristic approach based on Shannon’s expansion is provided in this study to offset the effect of temperature. Following bi-partitioning, the co-factored sub-circuits are transformed into cutting-edge AND-Inverter Graphs (AIGs) based on multi-level logic. The MCNC benchmark synthesis results indicate a maximum improvement of 36% area and 21.51% power density over the espresso tool-based decomposition.
