Peak power estimation of VLSI circuits: new peak power measures

International Symposium on Low Power Electronics and Design, 1997, pp. 178-183 K2: An Estimator for Peak Sustainable Power of VLSI Circuits

New measures of peak power in the context of sequential circuits are proposed. This paper presents an automatic procedure to obtain very good lower bounds on these measures as well as the actual input vectors that attain such bounds. The initial state of the circuit is an important factor in determining the amount of switching activity in sequential circuits and is taken into account. A peak po...

Genetic Spot Optimization for Peak Power Estimation in Large VLSI Circuits

Estimating peak power involves optimization of the circuit’s switching function. The switching of a given gate is not only dependent on the output capacitance of the node, but also heavily dependent on the gate delays in the circuit, since multiple switching events can result from uneven circuit delay paths in the circuit. Genetic spot expansion and optimization are proposed in this paper to es...

Estimation of Peak Current through CMOS VLSI Circuit Supply Lines

|We present a new approach for estimating the maximum instantaneous current through the power supply lines of CMOS VLSI circuits. Our nal goal is to determine the peak currents and voltage drops through power supply lines of real VLSI circuits within a practical time. Our approach is based on the iMax algorithm[1] of estimating the upper bound of the current, and uses an improved timed ATPG-bas...

Estimation of peak power dissipation in VLSI circuits using thelimiting distributions of extreme order statistics

In this paper, we present a statistical method for estimating the peak power dissipation in VLSI circuits. The method is based on the theory of extreme order statistics applied to the probabilistic distributions of the cycle-by-cycle power consumption, the maximum likelihood estimation, and the Monte-Carlo simulation. It enables us to predict the maximum power in the space of constrained input ...
