Example 15. Set output delay to PFL II IP output pins
Example below sets the output delay for the
• You don't have to constraint the path when this signal feeds arbiter logic or device tristate logic,

You don't have to constraint the path when this signal feeds the

• You can constraint the path when this signal feeds the processor or an external device controls.
