Due to a problem in the document SDC and TimeQuest API Reference Manual, you may find this sentence with an incorrect description of set_max_skew:
set_max_skew timing constraint is not affected by set_max_delay,set_min_delay and set_multicycle_path but it does obey set_false_path and set_clock_groups.
The correct description of set_max_skew should be as below:
The constraint set_max_skew is affected by set_false_path and set_clock_groups: paths cut by a false path will not be analyzed for skew, and no two paths will be compared for skew if their clocks are exclusive to each other.
