摘要： A method and a system for characterizing an integrated circuit (IC) design are disclosed. The method includes receiving a description of leaf cells used in the IC design. The IC design is described in a high-level language by using the description of the leaf cells. The description of the IC design includes specifying placement of the leaf cells and specifying connectivity between them. Further, the method includes extracting a circuit netlist file based on the physical layout of the IC design. The instructions are defined in the high-level language to perform simulations on the extracted circuit netlist file. These simulations are performed on the circuit netlist file to determine the values of the design parameters. Furthermore, the method includes providing the values of the design parameters of the IC design in a pre-defined output format based on the simulations.

摘要翻译： 公开了一种用于表征集成电路（IC）设计的方法和系统。 该方法包括接收IC设计中使用的叶细胞的描述。 通过使用叶细胞的描述，以高级语言描述IC设计。 IC设计的描述包括指定叶单元格的布局并指定它们之间的连通性。 此外，该方法包括基于IC设计的物理布局提取电路网表文件。 指令以高级语言定义，以对提取的电路网表文件进行仿真。 这些模拟在电路网表文件中执行，以确定设计参数的值。 此外，该方法包括基于模拟以预定义的输出格式提供IC设计的设计参数的值。
