The program provides a menu in nios-terminal, as shown in
interface. With the menu, users can perform the test for the temperatures sensor and external PLL.
Note, pressing ‘ENTER’ should be followed with the choice number.

In temperature test, the program will display local temperature and remote temperature. The remote
temperature is the FPGA temperature, and the local temperature the board temperature where the
temperature sensor located.
In the external PLL programming test, the program will program the PLL first, then use TERASIC
QSYS custom CLOCK_COUNTER IP to count the clock count in a specified period to check
whether the output frequency is changed as demanded. To avoid a Quartus II compilation error,
dummy transceiver controllers are created to receive the clock from the external PLL. Users can
