Embodiments include systems and methods for implementing a dummy fill flow in a processor design that points to a library of fill shapes that are associated with (e.g., defined and supported according to) a particular foundry process. For example, a set of cell types is generated in accordance with a foundry process definition, so that each unit cell type has a unique type identifier and an associated polygon definition. These cell types can be stored as a cell library. An automated fill flow can generate a dummy fill of an integrated circuit geometry with respective shape fills having shape cells that each point to one of the cell types in the cell library. Some implementations can use the cell library to stream in and instantiate the fill in the geometric design of the integrated circuit.

Unit fill for integrated circuit design for manufacturing

A system for verifying that device fingers of a semiconductor circuit have been properly represented by a corresponding layout diagram. The system determines a plurality of sub-circuits, from within a netlist of a schematic diagram, to be verified. Each sub-circuit of the plurality of sub-circuits includes a multi-finger device. The system also determines a first number of fingers included in the plurality of sub-circuits as represented by the schematic diagram. The system also determines a second number of fingers included in the plurality of sub-circuits as represented by the corresponding layout diagram. The system compares the first number of fingers against the second number of fingers. The system reports an error if the first number of fingers does not correspond to the second number of fingers.
