Chapter 6
Examples For FPGA
his chapter provides examples of advanced designs implemented by RTL or Qsys on the TSoM
board. These reference designs cover the features of peripherals connected to the FPGA, such as
A/D Converter. All the associated files can be found in the directory \Demonstrations\FPGA of
TSoM System CD.
Installation of Demonstrations
Install the demonstrations on your computer:
Copy the folder Demonstrations to a local directory of your choice. It is important to make sure the
path to your local directory contains NO space. Otherwise it will lead to error in Nios II.
Note Quartus Prime v17.1 or later is required for all TSoM demonstrations to support Cyclone V
SoC device.

This section gives instructions to program the HDMI transmitter to generate video pattern and audio
source. The entire reference is composed into three parts: video design, audio design, and I2C
design. A set of built-in video patterns and audio serial data will be sent to the HDMI transmitter to
drive the HDMI display with speaker. Users can hear the beeping sound from the speaker when
SW0 is set to 1 on the TSoM board. The resolution can be switched by pressing KEY1.
System Block Diagram
shows the system block diagram of this reference design. The HDMI Transmitter is
configured via I2C interface by I2C Controller and I2C HDMI Config. It is necessary to configure
the HDMI transmitter according to the desired settings.
An interrupt mechanism called Hot Plug Detect (HPD) is implemented in I2C HDMI config. to
re-configure HDMI transmitter when HPD interrupt occurs.
The Video Patter Generator was designed to send video patter to HDMI transmitter. Its resolution
can be changed by pressing KEY1. There must be a PLL Reconfig. To change the PLL dynamically
to support different resolutions. The Audio PLL and Audio Generator were designed to send audio
pattern to HDMI transmitter. The audio is transmitted via I2S interface in this demo. Users can
choose to enable audio generator or not through SW0.
