Abstract:
In
Multiple Supply Voltage design, the tasks of island partitioning
and voltage level assignments should be done simultaneously
in the floorplanning process in order to take those important
physical information into consideration. In this paper,
we consider this core-based voltage island driven floorplanning
problem including islands with power down mode, and propose
a method to solve it. Given a candidate floorplan solution
represented by a normalized Polish expression, we are able
to obtain optimal voltage assignment and island partitioning
simultaneously to minimize the total power consumption.
Simulated annealing is used as the basic searching engine.
Extensive experiments demonstrate the effectiveness of our
approach.
