How to get all group_paths?

[evmanz]

Hi!

I want to know, programmatically, what group_paths exist in the design.

For example, in Synopsys's PrimeTime you have the get_path_groups command, which returns all the group_paths that exist. One of the use cases is to iterate over timing_paths that belong to a specific group_path, etc.

Is there anything like that in OpenSTA?
