This section defines the constraint requirements for the core. Constraints are provided in several XDC files which are delivered with the core and the example design to give a starting point for constraints for the user design.
There are four XDC constraint files associated with this core:
•<corename>_example_design.xdc
•<corename>_ooc.xdc
•<corename>.xdc
•<corename>_clocks.xdc
The first is used only by the example design; the second file is used for Out Of Context support where this core can be synthesized without any wrappers; the third file is the main XDC file for this core.
