Abstract: Disclosed are methods, systems, and computer program products for performing grid morphing technique for computing a spreading of objects over an area such that the final locations of the objects are distributed over the area and such that the final locations of the objects are minimally perturbed from their initial starting locations and the density of objects meets certain constraints. The minimization of perturbation, or stability, of the approaches disclosed, is the key feature which is the principal benefit of the techniques disclosed. The methods described herein may be used as part of a tool for placement or floorplanning of logic gates or larger macroblocks for the design of an integrated circuit.

Abstract: Disclosed are a method, system, and computer program product for implementing incremental placement for an electronic design while predicting and minimizing the perturbation impact arising from incremental placement of electronic components. In some embodiments, an initial placement of an electronic design is identified, the abstract flow is computed, the target locations of various electronic components to be placed are identified, the relative ordering of electronic components are determined, and the placement is then legalized. Furthermore, in various embodiments, the method, system, or computer program product starts with an initial placement of an electronic design and derives a legal placement by using the incremental placement technique while minimizing the perturbation impact or the total quadratic movement of instances.
