Abstract
A method of pin placement for an integrated circuit includes the steps of (a) receiving as input a corresponding set of pin constraints for each pin of a hard macro, (b) receiving as input a specification for the hard macro, (c) locating pin slots on each side of the hard macro, (d) finding at least one of a horizontal interval and a vertical interval on a side of the hard macro for each pin of the hard macro, and (e) assigning each pin of the hard macro to a pin slot within the horizontal interval and the vertical interval that satisfies the corresponding set of pin constraints.
