Abstract: This paper proposes a novel system-level power estimation methodology for electronic designs consisting of intellectual property (IP) components. Our methodology relies on analytical output and power macromodels of the IP blocks to estimate system dissipation without petforniing any simulation. We derive upper bounds on the estimation error of our methodology and demonstrate the relation of this error to the sensitivities of the macromodeling functions. For circuits without feedback, we give a siijj'icient con… Show more

“…Consider the adder unit. Based on its inputs, the p, d, and s values are computed using the technique described in Liu and Papaefthymiou [2001]. For the inputs 0 + 1, the computed p, d, and s values are 0.017, 0.031, and 0.061, respectively.…”

“…We used the Markov chain-based sequence generator described in Liu and Papaefthymiou [2001] that converts the probabilistic p, d, and s values into an actual sequence of test vectors for use in simulation. Measurements were taken at 0.1 intervals ranging from 0.05 to 0.95 in each probabilistic dimension.…”

“…The macromodel construction consists of generating a mapping between the power dissipation of a circuit and certain statistics of the input signals. This technique has been proven to be effective for individual IP components building IP power models [1]. The urgent need of a feasible IP power model is becoming more useful in recent years.…”

“…The average power dissipation Psystem Test IP-based system.We compare the estimated power Psystem in(6)with the simulated power estimation to evaluate the accuracy of the power macromodel function in(1). The reference values of the circuit's power dissipation are obtained using time delays from the Synopsys PowerCompiler.…”
