3. Select the AVRIoSelects tab on the right-hand side of the dialog box.
4. Select the LOAD signal from the Input Design Ports and then select IOSELA0
from the AVRIoSelects.
5. Press Connect to connect the counter's LOAD signal to FPGA-AVR I/O Select 0.
6. Connect the remaining inputs and outputs as shown in Table 4-2.
7. Uncheck Generate Template Test Bench File on the bottom left-hand side of the
Select Ports dialog. Since we are not performing co-verification, it is not neces-
sary to generate the pre-layout test bench file.
8. Press OK.
