The-sourceoption specifies the name of a node in the clock path that you use as reference for your generated clock. The source of the generated clock must be a node in your design netlist, and not the name of a clock you previously define. You can use any node name on the ...

I am trying to use the create_generated_clock directive to create the additional clock for TimeQuest, I have looked though the help and have tried various options, but I can't get the syntax right Can someone help me with the syntax please? e.g., what is the correct ...
When you do a create_generated_clock, it takes that PLL clock and uses it for the generated waveform. Since it found the correct clock, and I assume you have a -divide_by 1000 option, then it should be able to get 1khz. The second thing it does is tries to find the path f...
