Power consumption is a primary concern for today's IC designers. However, determining an IC's power consumption is a difficult task, as consumption varies according to input stimulus conditions. This paper will focus on (1) the principal phenomena involved in the power consumption of CMOS circuits, (2) a brief survey of power estimation techniques, and (3) the effect of power-supply noise on circuit performance plus possible solutions to this problem.

Abstract The light emission from ever increasing OFF-state leakage currents in advanced CMOS technologies can now be reliably measured using existing photon detectors. The measurements of such an emission provide valuable information about the operation of ICs. In this paper we suggest and experimentally confirm two new techniques based on such measurements - Transient Logic State Detection and Power Supply Noise Analysis.

Abstract Power supply noise (PSN) is becoming more severe as technology scales, and can cause signal distortion and increase gate delay. This can further result in improper circuit operation. In this paper, we propose a novel approach based on ATE (automatic test equipment) that teaches neural networks (NN) to correctly classify a set of worst case input patterns with respect to the maximum instantaneous current. This can be thought of as a learning behavior of chip power consumption change due to different input patterns. Then a genetic algorithm (GA) was applied to further optimize this set of NN worst case patterns. A final set of worst case patterns were expected to detect a small critical sequence of high switching currents that was directly related to the worst case power supply noise. This novel diagnosis approach can efficiently identify the defective design or weakness due to PSN as well as locate the defect or weaknesses within the design.
