Estimating energy consumption in logical CMOS circuits based on their switching activity

Estimating energy consumption in logical CMOS circuits based on their switching activity The relationship between energy consumption and switching activity of logic circuits built of CMOS-based gates from the library of custom VLSIC designing. The switching activity of the logic circuit, i.e., total number of switched transistors integrated into the circuit is counted for a certain sequence of input signals sets. It is suggested to estimate energy consumption in the synthesized logic CMOS circuit based on the parameter of its switching activity, thus, avoiding time-consuming circuit simulation. The results of experiments on various ways of estimating energy consumption in combinational circuits at the stage of logical designing are described and compared with the results of circuit simulation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Microelectronics Springer Journals

Abstract

The relationship between energy consumption and switching activity of logic circuits built of CMOS-based gates from the library of custom VLSIC designing. The switching activity of the logic circuit, i.e., total number of switched transistors integrated into the circuit is counted for a certain sequence of input signals sets. It is suggested to estimate energy consumption in the synthesized logic CMOS circuit based on the parameter of its switching activity, thus, avoiding time-consuming circuit simulation. The results of experiments on various ways of estimating energy consumption in combinational circuits at the stage of logical designing are described and compared with the results of circuit simulation.
