POWER ESTIMATION METHOD FOR HIGHLY CORRELATED INPUT SEQUENCES UNDER REALISTIC DELAY MODEL

A new power estimation method is presented which considers spatio-temp oral correlations among the primary inputs as well as the glitch effec t under a realistic delay model. To deal with the glitch effect, the s ymbolic simulation technique is employed, and to take the correlations among the primary inputs into account, the authors employ a new techn ique which transforms correlation information into a logic structure, called 'pre-logic.' Experimental results show that the estimation erro r of the proposed method is similar to 4% under a realistic delay mode l with highly correlated input streams.
