  • Publication number: 20240113809
    Abstract: The present application provides an instruction encoding-based data processing method and apparatus, and a device. N-path error correction encoding is performed on an instruction in information to be processed to obtain N encoded instructions, the encoded instructions and encoded meta channel programs obtained by the error correction encoding are used to perform redundant processing on data to be processed to obtain N pieces of response data, and then error correction decoding is performed on the N pieces of response data to obtain processing result information of the information to be processed. Because the N encoded instructions are heterogeneous and the encoded meta channel programs used in the N-path processing are heterogeneous, the randomness of the processing process can be improved, generalized disturbance in the data processing process can be corrected in combination with the error correction encoding and decoding methods, and thus the security of data processing is improved.

  • Patent number: 10546090
    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.

  • Patent number: 10474781
    Abstract: Layout simulation and verification of a semiconductor chip can require extensive design rule checking (DRC) and design rules for manufacturing (DRM) analysis of the design in order to ensure proper operation. DRC and DRM can be expensive in terms of computational time and resource usage. To mitigate some of the cost, a virtual layer can be constructed for a cell instance identified in the semiconductor design. Shapes including rectangles and polygons can be determined which traverse the cell instance and are from other hierarchical layers of the design. The shapes can be combined to generate a virtual layer used for simulation, validation, DRC, DRM, etc. The virtual layer can be augmented with traversing shape information from other instances of the cell. The rectangles, polygons, and complex polygons can be combined to simplify the virtual layer. Multiple virtual layers can be generated for the simulation and validation processes.

  • Patent number: 9881114
    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.
