Abstract: Hierarchical design levels describe semiconductor designs and define architecture, behavior, structure, function, etc. for the designs. A virtual cell model based on cells populating a design is constructed and used for purposes including design simulation, analysis, verification, validation, and so on. A cell and multiple instances of the cell are identified across a design. An empty cell model comparable to the identified cell is created. A compressed representation of unsolved geometric data based on the identified cell data and a virtual hierarchical layer (VHL) are generated as model data, and the model data is placed into the empty cell model. As a result of the placement of the model data, a virtual cell model is created.

Abstract: A virtual hierarchical layer (VHL) is constructed for a semiconductor design in order to reduce the computational requirement of design rules checking (DRC) and design rules for manufacture (DRM) procedures. In order to form the VHL, a negative plane is created. A cell and multiple instances of the cell are then identified in the semiconductor design and polygons which overlap the cell and its instances are determined. The polygons are pushed into the negative plane to create holes in the plane. Shapes overlapping other instances of the cell which fall onto holes in the solid virtual cell plane are ignored. The resulting holed solid virtual cell plane can then be inverted to create a VHL to be used for design simulation and verification.

Abstract: Simulation and verification are critical to analyzing a semiconductor design using design rule checking (DRC) to verify design rules for manufacturing (DRM). The efficient use of computational resources including runtimes and resource requirements is a key component of the analysis. A virtual hierarchical layer (VHL) with shapes is generated for the design analysis of a design, including cells and hierarchical design levels. A cell and multiple instances of the cell are identified in the design. A VHL based on polygons overlapping the cell is generated in response to an algorithmic operation. The VHL shapes are propagated to subsequent algorithmic operations. The algorithmic operations update the VHL shapes. Shapes are filtered out of the VHL shapes as part of the updating. The VHL shapes are propagated through a chain of operations.
