Timing constraints

[Altera_Forum]

Hi, 

 I followed instructions on the toutorial for Time Quest Analyzer, in order to put a constraint on my clock input to the design.  I chose the clock (clock_50), and gave it a 10ns constarint.  still i get the following - Warning (332060): Node: CLOCK_50 was determined to be a clock but was found without an associated clock assignment. can anyone advise?

You didn't show your constraint, but SDC is case sensitive by default. (I think there's a -no_case option with a lot of them).

Hi, 

thanks for the answer..  here is the constraint (BTW, i generated it through the create clock option in the Time Quest Analyzer GUI):  # ************************************************************** # Time Information # **************************************************************  set_time_format -unit ns -decimal_places 3    # ************************************************************** # Create Clock # **************************************************************  create_clock -name {CLOCK_50} -period 10.000 -waveform { 0.000 5.000 } [get_ports {CLOCK_50}]   # ************************************************************** # Create Generated Clock # ********

Did you include the .sdc file on your project? (Assignments -> Settings -> Timequest Timing Analyzer)
