Critical Issue
Description
In the Quartus® II software versions 11.0, in the TimeQuest Timing Analyzer, the rise_from_clock, rise_to_clock, fall_from_clock and fall_to_clock options of the set_max_skew constraint do not properly constrain the design.
Resolution
Use the from_clock and to_clock options and use an explicit clock collection instead of "*". For example, use [get_clocks *] or [all_clocks] instead of "*".
This issue is corrected in the Quartus II software version 11.0 SP1.
