NIOS Based Example Codes

There are several NIOS based examples for users to get started and try them on the MAX 10 Plus
board.  All  the  NIOS  based  examples  can  be  found  in  the  system  CD  under  the  folder  named
Demonstrations.  Users  are  free  to  use  or  modify  these  examples  for  personal  use  or  education
purpose.
Note: The output files generated after compilation in Quartus II e.g. .sof and .pof files, are saved in
the  folder  "output_files"  under  the  directory  of  demo  project.  The  workspace  of  Nios  II  Eclipse
project is located in the folder "software" under the directory of demo project.

Power Monitor

The power monitor demo shows how to measure the power consumed through the onboard power
monitor chip LTC2990. There are three LTC2990 to monitor the following power rails:

•

3.3V VCCIO

•

2.5V Core

•

2.5V VCCIO

•

1.5V VCCIO

•

1.2V VCC

The power monitor chip LTC2990 communicates with the FPGA via I2C protocol. The I2C
OpenCore IP is used in this demonstration for the MAX 10 device to communicate with the three
LTC2990, which have different I2C slave address 98h, 9Ah, and 9Ch.

◼

Block Diagram

shows the system block diagram of this demonstration. The NIOS program is stored in

the onchip memory and the Nios II processor is running at 50MHz. The I2C library is located in the
files named I2C_core.cpp and I2C_core.h. The I2C OpenCore IP is located in the folder
“ip/i2c_opencores” under the project directory.
