6.1.4.2. Updating Entity Auto-Discovery

All editions of the Quartus® Prime and Quartus II software search your project directory for undefined entities. For example, if you instantiate entity “sub” in your design without specifying “sub” as a design file in the Quartus Settings File (.qsf), synthesis searches for sub.v, sub.vhd, and so on. However, Quartus® Prime Pro Edition performs auto-discovery at a different stage in the flow. Ensure that your RTL code accommodates these auto-discovery changes.
