Vivado synthesis has the following limitations when instantiating a Verilog module in a VHDL design unit:

• Use explicit port association. Specify formal and effective port names in the port map.

• All parameters are passed at instantiation, even if they are unchanged.

• The parameter override is named and not ordered. The parameter override occurs through instantiation, and not through defpas .

• Only component instantiation is supported when instantiating a Verilog module in VHDL. Direct entity instantiation is not supported.
