Thermal-driven Circuit Partitioning and Floorplanning with Power
Optimization
In this paper, we present methodology to distribute the temperature of gates
evenly on a chip while simultaneously reducing the power consumption by using
newly designed partitioning and floorplanning algorithms. This new partitioning
algorithm is designed to partition blocks with well-balanced temperatures by
altering the FM algorithm to include thermal constraints. Then, the suggested
floorplanning algorithm can assign specific geometric locations to the blocks to
refine the quality of the thermal distribution and to reduce power consumption.
The combination of these two new algorithms, called TPO, is compared with the
results of a conventional design procedure. As a result, power is reduced by up
to 19% on average and a well-distributed thermal condition is achieved.
