After exploring the possible workarounds, there are currently two ways to suppress the message.


1. Using the QSF Assignments

Add the following assignments in your .qsf file:

set_global_assignment -name MESSAGE_DISABLE <value>

set_global_assignment -name MESSAGE_DISABLE -entity <entity name> <value>

set_instance_assignment -name MESSAGE_DISABLE -to <to> -entity <entity name>

Note: <value> refers to the Info ID of the message you want to suppress.


2. Using the GUI

Open the GUI and suppress the message as shown in the snapshot. A .srf file will be created in the design folder.

The next time you run the design, the suppressed messages will no longer be displayed.


However, if the customer removes the QSF assignments or the .srf file, the message will reappear.

This method is not a foolproof encryption solution but merely a way to suppress the messages.
