چکیده
|
Dynamic power estimation is essential in designing vlsi circuits where many parameters are involved but the only circuit parameter that is related to the circuit operation is the nodes' toggle rate. this paper discusses a deterministic and fast method to estimate the dynamic power consumption for cmos combinational logic circuits using gate-level descriptions based on the logic pictures concept to obtain the circuit nodes' toggle rate. the delay model for the logic gates is the real-delay model. to validate the results,the method is applied to several circuits and compared against exhaustive,as well as monte carlo,simulations. the proposed technique was shown to save up to 96% processing time compared to exhaustive simulation. © 2015.
