Abstract

A system generally including a clock structure analysis tool, a static timing analysis tool and a waveform tool is disclosed. The clock structure analysis tool may be configured to generate a simplified clock structure for a clock signal in a complex clock structure in a design of a circuit. The static timing analysis tool may be configured to generate a plurality of results for a plurality of intermediate signals in the simplified clock structure in response to a static timing analysis of the design. The waveform tool may be configured to generate a first representation in a graphical user interface format of the intermediate signals and the results.
