Abstract

An electronic design automation method of placing circuit components of an integrated circuit ('IC') is provided. A synthesized circuit netlist including one or more soft macros is received and a rough global placement of this netlist is performed. A shaper function is determined. The shaper function evaluates a cost of a current placement of the one or more soft macros based on one or more constraints and one or more penalty functions which are associated with the one or more constraints. Moreover, the current placement is optimized to produce a subsequent placement of the one or more soft macros by minimizing the cost. Furthermore, where the netlist includes one or more hard macros, a legalization requirement is applied to the one or more hard macros.
