Abstract :
When designing integrated circuits, sub-components rarely end up being perfectly rectangular. However, currently most block-placers only consider rectangular components, resulting in inefficient area utilization. We propose a placement tool that allows arbitrarily sized and shaped convex components. It extends the rectangle-packing method proposed by Kajitani. We describe the methods used to create the placement and give some performance results
