Set Unused Pins in Your Design
When compiling designs, Altera recommends that all unused pins act as tri-stated inputs.
To change this setting in the Quartus II software, perform the following steps:
1. Choose Device (Assignments menu).
2. On the Device page of the Settings dialog box, click Device and Pin Options.
3. In the Device & Pin Options dialog box, click the Unused Pins tab.
4. Under Reserve all unused pins, select As Inputs, tri-stated (Figure 2).
5. Click OK.

The Quartus II software default settings configure unused pins as outputs driving ground.
Board components may be damaged by having GND signals driven onto pins that drive
Vcc.
