Abstract
Techniques and systems for performing clock tree synthesis (CTS) across multiple modes are described. Some embodiments traverse one or more clock trees from the root of each clock tree to a set of sinks of the clock tree. During the traversal, each clock gate can be marked with a traversal level, and each sink can be marked with one or more clocks and one or more modes that are associated with the sink. A task queue can then be created based on the information collected during the clock tree traversal and populated with different types of tasks based on skew balancing requirements across different modes, and the task queue can be provided to a CTS engine to achieve high-quality skew-balanced clock trees across all modes.
