Can Encounter add some delay elements automatically ?!

amrzahir
I want to add some delay in an input path to the design. The problem is a hold violation, the input data changes before registering it. In other words, what is the constraint to be given to Encounter to add a delay (fix the hold violation on the input ports). Thanks

  • If I follow your situation correctly, this type of violation should be fixed by the tool automatically with "optDesign [-postCTS | -postRoute] -hold".  You shouldn't have to add any special constraints to the design other than create_clock statements for the launching port and capturing register and a set_input_delay constraint on the input port.

    If you can see the violation reported, then optDesign should try to fix it.

    Hope this helps,
    Bob
