Examining Clock Paths in an Abstract Clock Graph
The abstract clock graph view allows you to visualize the relationships between clocks
and between the driving cells and output loads in a clock network. You can view the
relationships between primary and generated clocks, the convergence of multiple clocks,
and the fanout of clocks to multiple sequential elements.
An abstract clock graph is similar to a clock schematic but with a higher level of
abstraction. You can focus on key characteristics of the clock network while ignoring
irrelevant objects, which can help you to selectively debug problems.
The following diagram shows an example of an abstract clock graph window.
