Disclosed is an improved method, system, and computer program product for performing core placement when presented with an I/O ring design. A multi-pass approach is taken to place and shape core objects into the available core area formed by the inner surface of the I/O ring. The multi-pass approach permits very fast placement of the core objects, which still provides for an accurate estimation of the die size and configuration requirements for the electronic design. Moreover, the present approach allows core objects to be placed in a way that retains any preferred affinities for the objects to be located near other objects, e.g., near specific I/Os on the I/O ring.
