An approach is disclosed herein for balancing layer densities in using an automated process. The approach disclosed herein operates on a region-by-region and layer-by-layer basis to perform parameterized layer balancing. In some embodiments, the process comprises determining densities of respective layers in respective regions, evaluating each layer and region to determine whether operations need to be taken to balance those layers in the corresponding regions, determining what those actions should be, and then implementing those actions. Additionally, in some embodiments, the process may operate in different orders and may be associated with a looping flow until a layout being processed has been balanced.

Method, product, and system for automated, guided, and region-based layer density balancing

A method is provided that includes receiving shape data specifying a shape of an electromagnetic (EM) structure in a circuit layout and transferring the shape data to a schematic cell representation based on a logic function of the EM structure and package technology layers of the circuit layout. The method includes placing a symbol for the EM structure in the schematic cell representation, associating the shape data and a model path with a cell parameter in the symbol, mapping the shape data to the package technology layers, and specifying pins in the schematic cell representation according to the shape data. Further, the method includes verifying ports for the EM structure and placing the EM structure in a package layout for a printed circuit board (PCB). A system and a non-transitory, computer readable medium storing commands to perform the above method are also provided.
