PHYSICAL INFORMATION EXTRACTION REFLECTION METHOD, HIERARCHICAL CIRCUIT INFORMATION WITH PHYSICAL INFORMATION USING IT, AND CIRCUIT DESIGNING METHOD

摘要

PPROBLEM TO BE SOLVED: To realize speeding up of circuit simulation and decrease of data quantity by reflecting in hierarchical circuit information the physical information extracted from layout information while maintaining a hierarchy structure, generating hierarchical circuit information with physical information, and thus reflecting to the circuit information of the hierarchical structure while maintaining accuracy. PSOLUTION: This method includes a physical information extraction process for extracting information regarding physical condition in a single unit such as element, cell, such as a parasitic element, a parasitic coupling element, a shape parameter of a device, and performance or property of the device, from layout information, or physical information and a physical information reflection process for reflecting the physical information to the circuit information consisting of hierarchy and acquiring the hierarchical circuit information while maintaining the hierarchical structure.
