Vivado Design Suite User Guide: Synthesis (UG901)

A design can contain EDIF files generated by:

  • Synthesis tools
  • Schematic text editors
  • Any other design entry mechanism

These modules must be instantiated to be connected to the rest of the design. Use BLACK_BOX instantiation in the HDL source code.

Vivado synthesis lets you apply specific constraints to these BLACK_BOX instantiations. After you make a design a BLACK_BOX, each instance of that design is a BLACK_BOX. Download the coding example files from Coding Examples.
