    The original project and the example QAR have the same warning: :)

    I'm sorry, but I don't see this critical warning when I synthesize this.

    I attached the project with the report files (.rpt) when you look in the Static Timing Analyzer report (.sta.rpt) you will see that there is no such warning.

    Which version of Quartus are you using? The example you gave me was created for version 11.0. I use 11.1 with service pack 2.
