Intel® Quartus® Prime Standard Edition User Guide: Platform Designer
5.7.3. Name HDL Signals for Automatic Interface and Type Recognition in the Platform Designer Component Editor
To enable auto-recognition, you must create signal names using the following naming convention:
<interface type prefix>_<interface name>_<signal type>
Specifying an interface name with <interface name> is optional if you have only one interface of each type in the component definition. For interfaces with only one signal, such as clock and reset inputs, the <interface type prefix> is also optional.
