2.2.1. Passing Parameter Information from Verilog HDL to VHDL
You must use in-line parameters to pass values from Verilog HDL to VHDL.
By default, the x_on_violation_option logic option is enabled for all design registers, resulting in an output of “X” at timing violation. To disable “X” propagation at timing violations on a specific register, disable the x_on_violation_option logic option for the specific register, as shown in the following example from the Intel® Quartus® Prime Settings File (.qsf).
set_instance_assignment -name X_ON_VIOLATION_OPTION OFF -to \ <register_name>
In-line Parameter Passing Example
lpm_add_sub#(.lpm_width(12), .lpm_direction("Add"), .lpm_type("LPM_ADD_SUB"), .lpm_hint("ONE_INPUT_IS_CONSTANT=NO,CIN_USED=NO" )) lpm_add_sub_component ( .dataa (dataa), .datab (datab), .result (sub_wire0) );
Note: The sequence of the parameters depends on the sequence of the GENERIC in the VHDL component declaration.
