Abstract
Globally placing a circuit design includes adjusting indicated capacity levels for placement bins associated with a target integrated circuit, based on first levels of demand for resources by instances in the circuit design in regions of the target IC. Region constraints restrict placement of the instances in the regions, and the regions include two or more two or more overlapping regions. Tracked levels of demand for resources in the placement bins are adjusted, after adjusting the indicated capacity levels, based on the indicated capacity levels, a target utilization level of the resources in the placement bins, and a current placement. The current placement of the instances is updated based on a density gradient of an electrostatics-based model of the tracked levels of demand, and repeating adjusting the tracked levels of demand and updating the current placement are repeated in response to the density gradient failing to satisfy a threshold.
