1. Downloading to Altera Nios Development Kit CSCE 488 Witawas Srisa-an

2. Documents Needed I’m providing you with a copy of “Nios Development Board: Reference Manual, Stratix Edition”. –contain all the basic I/O pins for Stratix device –overview of programming configurable device with Quartus –overview of the default configuration that comes with the kit.

3. Before We Start… Make sure you have the following issues resolved –install Quartus with appropriate license (either web or seat license) –have a working byteblaster MV or byteblaster II –install byteblaster driver http://www.altera.com/support/software/drivers/dri-bb-xp.html

4. Custom Design in Nios Dev. Kit In this exercise, we will use schematic capturing tool to build an output driver for the board –test push buttons –test LED displays –test 7 segment displays

5. Our Simple Driver

6. Compile the Design Just use compiler tool to compile the design Once successful, perform the Pin Assignment Check the name of each I/O pin from the manual. For example, LED D0 is corresponding to pin H27 (page 27)

7. Pin Assignment

8. Pin Assignment (cont.) assign LED D0 – D3 for out1-out4 assign sw3 for sw input and D7 for out5 assign the first decimal place for clk_out and sw0 for reset input Look at figure 21 on page 35 and select the assignment for clk input Recompile your design. Once successful, go to tool menu and select programmer

9. Programmer Must be checkedmust be the same as your project

10. Programmer (cont.) If your byteblaster driver is installed correctly, you should see download progress bar moving. Once complete, your design is downloaded to the board.

11. PROBLEM! I see my design download to the board but I don’t see the LEDs light up –none of the push buttons are working –the decimal point on the 7-segment display is not flashing

12. The configuration is wrong go to assignments->devices->device & pin options. Make sure you have selected “Reserve all unused pins” as “inputs, tri-stated”

13. Select Unused Pins

14. Finishing Up Recompile your design Try programmer again, this time it should work

17. Restoring Factory Setting Most likely, your board does not have the factory setting –refer to Appendix B for more information NOTICE! You must install SOPC builder to be able to restore factory setting
