Model-based refinement of the placement process in integrated circuit generation

A system performing model-based refinement of a placement of components in integrated circuit generation, the system comprising:

• a memory device configured to store an initial placement of the components;
• and
• a processor configured to select one of the components as a candidate component and postulate a move of the candidate component from an original position in the initial placement to a new position, to define one or more nets associated with the candidate component, wherein each of the one or more nets includes one or more of the components connected to one or more connections originating at the candidate component, to define an initial perimeter and a new perimeter associated with each of the one or more nets, wherein the initial perimeter for each net is drawn to include every one of the one or more components included in the net and the candidate component at its original position and the new perimeter is drawn to include every one of the one or more components included in the net and the candidate component at its new position, to perform computations to quantify a change from the initial perimeter and the new perimeter and the original position and the new position, and to obtain a model of wires interconnecting the candidate component to the one or more components of each of the one or more nets based on a result of the computations, wherein a result of the placement is provided for manufacture of the integrated circuit.

A computer program product for performing model-based refinement of a placement of components in integrated circuit generation, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to perform a method comprising:

• selecting one of the components as a candidate component and postulating a move of the candidate component from an original position to a new position;
• defining one or more nets associated with the candidate component, wherein each of the one or more nets includes one or more of the components connected to one or more connections originating at the candidate component;
• defining an initial perimeter and a new perimeter associated with each of the one or more nets, wherein the initial perimeter for each net is drawn to include every one of the one or more components included in the net and the candidate component at its original position and the new perimeter is drawn to include every one of the one or more components included in the net and the candidate component at its new position;
• performing computations to quantify a change from the initial perimeter and the new perimeter and the original position and the new position;
• and
• obtaining a model of wires interconnecting the candidate component to the one or more components of each of the one or more nets based on a result of the computations, wherein a result of the placement is provided for manufacture of the integrated circuit.
