Abstract: An efficient electronic structure for circuit design, testing and/or manufacture for validating a cell layout design using an intelligent engine trained using selectively arranged cells selected from a cell library. An initial design rule violation (DRV) prediction engine is initially trained using a plurality of pin patterns generated by predefined cell placement combinations, where pin patterns are pixelized and quantified and is classified as either (i) a DRV pin pattern (i.e., pin patterns likely to produce a DRV) or (ii) a DRV-clean pin pattern (i.e., pin patterns unlikely to produce a DRV).

Abstract: The present disclosure relates to a method and apparatus to create a physical layout for electron-beam lithography, comprising defining a layout grid for a physical design, the layout grid further comprising vertical grid lines which coincide with stitching lines resulting from partitioning the physical design into a plurality of subfields. The physical design is assembled in accordance with design restrictions regarding interaction between design shapes and the layout grid. In some embodiments, the design restrictions are realized though layout restrictions. In some embodiments, the design restrictions are realized by shifting standard cells to minimize design shape interaction with the layout grid in a post-layout step. In some embodiments, the design restrictions are realized by exchanging positions between a plurality of standard cells for an exchange permutation which minimizes the number of interactions in a post-layout step.
