Abstract

Power consumption has become a primary constraint of integrated circuit design. Many models have been proposed to evaluate dynamic and leakage power in every design level. However, how to accurately predict TPower, the total power with dynamic and leakage power included, for large-scale designs within reasonable time remains unsolved. In this paper, a new topic of vector extraction for power estimation is brought forward based on the distribution analysis of power consumption of different types. After extracted, a large number of vectors are compacted into much fewer without significant influence on the specified power property, which makes the application of accurate and fast simulator possible. For the purpose of validation, we use the method on average TPower vector extraction and obtain good experimental results.
