Abstract

In this paper, we propose the design of an ultra-fast temperature simulator (LightSim) that can perform both steady state and transient thermal analysis, and also take the effect of leakage power into account. We use a novel Hankel transform based technique to derive a transient version of the Green´s function for a chip, which takes into account the feedback loop between temperature and leakage. Subsequently, we calculate the temperature map of a chip by convolving the derived Green´s function with the power map. Our simulator is at least 3500 times faster than HotSpot, and at least 2.3 times faster than competing research prototypes [4, 12]. The total error is limited to 0.18 °C.
