Practical methodology for early buffer and wire resource allocation

摘要

A method, system, and computer program product for allocating buffer and wire placement in an integrated circuit design is provided. In one embodiment, the surface of a integrated circuit design is represented as a tile graph. Allocation of buffer locations for selected tiles in the tile graph is then received and nets are routed between associated sources and sinks. Buffer locations within selected tiles are then selectively assigned based upon buffer needs of the nets, wherein the nets are routed through selected tiles and assigned buffer locations using a cost minimization algorithm.
