2022.1 English

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.
