Set_output_delay min max
Web在UG903中,也有下面的描述:. Add Delay Input Delay Command Option The -add_delay option must be used if: • A max (or min) input delay constraint exists, and • You want to specify a second max (or min) input delay constraint on the same port. This option is commonly used to constrain an input port relative to more than one clock ... WebUse the Set Output Delay ( set_output_delay) constraint to specify external output delay requirements. Specify the Clock name ( -clock) to reference the virtual or actual clock. When specifying a clock, the clock defines the latching clock for the output port.
