Allows you to define a derived clock that is offset from the absolute clock by a specific value. For example, entering an offset of 1 ns indicates that transitions on the derived clock should occur 1 ns after transitions on the absolute clock. You can type a value in the Offset from base absolute clock fmax box and select a time unit from the list to indicate how much the Quartus^® II software should offset the absolute clock to define the current derived clock. If you do not specify a value for an offset clock, the Timing Analyzer detects and calculates the offset automatically, and uses this detected offset in delay calculations that determine whether the path met timing requirements. The offset value does not affect the duty cycle.
