Disclosed is a method, system, and computer program product for automated implementation of pipeline flip-flops in an electronic design. Two operating modes can be used either together or separately to implement pipeline flip-flops. An analysis mode is employed to perform a determination of the number of stages of pipeline flip-flops needed for particular portions of an electronic design. A placement stage is used to place the pipeline flip-flops in the layout.

Method and system for implementing pipeline flip-flops

The various embodiments of the present invention generally relate to systems, methods, and computer program products for placement of at least one cell in a digital integrated circuit layout. A global placement grid of coordinates is formed, where the coordinates represent horizontal and vertical directions. A local placement grid of coordinates is also formed for at least one local region, where the local placement grid of coordinates represent horizontal and vertical directions, and where the at least one local region is adapted to support non-integer multiple height rows. At least one cell is associated with the at least one local region formed, and the cell can be placed in the local placement grid of the local region.
