A practical CAD technique for reducing power/ground noise in DSM circuits
One of the fundamental problems in Deep Sub Micron (DSM) circuits is Simultaneous Switching Noise (SSN), which causes voltage fluctuations in the circuit power/ground networks. In this work we propose a CAD optimization technique to spread out the switching times of different gates in a circuit to reduce its SSN, by sizing them appropriately. We make sure that its critical delay does not increase while its p/g noise decreases. Our formulation is a Linear Programming one, which we have efficiently formulated and solved. On average, improvements of 28% in the maximum peak-peak voltage fluctuations in the power networks, and that of 20% in the ground networks were achieved by our method over the original circuit implementations. These results were obtained without any performance penalty. As a positive effect of gatesizing, the power dissipation in the optimized circuits, on average, was reduced to about half of the unoptimized ones for the same supply voltage. We have used standard comm...
