Abstract:
1. A timing analysis apparatus comprising: a circuit data acquisition section for acquiring circuit data regarding a circuit under analysis; the circuit under analysis being arranged to include a clock source, a mesh section that is coupled to the clock source and configured with wiring in a meshed form, and a clock supply destination that receives a clock signal from the clock source via the mesh section; a path setup section for setting up two paths extending from the clock source to the clock supply destination as a first path and a second path in accordance with the circuit data; a distance calculation section for calculating a coupling point-to-point distance between a first output terminal of the mesh section on the first path and a second output terminal of the mesh section on the second path; a global coefficient decision section for determining a global coefficient that indicates the degree of variation in time period from the moment when the clock signal is issued from the clock source until the moment when the clock signal reaches each output terminal of the mesh section; and a timing verification section for verifying clock supply timing at the clock supply destination in accordance with the global coefficient; wherein the global coefficient decision section determines the global coefficient in accordance with the coupling point-to-point distance.
