3.7.2. Pin Assignments
Set the pin assignments before you compile to provide direction to the Quartus® Prime software Fitter tool. You must also specify the signals that should be assigned to device I/O pins.
You can create virtual pins to avoid making specific pin assignments for top-level signals. This is useful when you want to perform compilation, but are not ready to map the design to hardware. Altera recommends that you create virtual pins for all unused top-level signals to improve timing closure.
Note: Do not create virtual pins for the clock or reset signals.
For GTS devices, use the GTS Channel Channel Placement tool to assist you in making pin assignments. Specify the transceiver mode and PMA direct NRZ.
