1 SDI II Design Example Quick Start Guide
The SDI II IP core design examples for Intel® Arria® 10 devices feature a simulating
testbench and a hardware design that supports compilation and hardware testing.
When you generate a design example, the parameter editor automatically creates the
files necessary to simulate, compile, and test the design in hardware.

1.2 Hardware and Software Requirements
Intel uses the following hardware and software to test the design examples:

Hardware
• Intel Arria 10 GX FPGA Development Kit
• SDI Signal Generator
• SDI Signal Analyzer
• SubMiniature version B (SMB) to Bayonet Neill–Concelman (BNC) cables for
single-rate and triple-rate designs, or BNC to BNC cables for multi-rate designs
• VIDIO™ FMC Development Module VIDIO-12G-A (Nextera 12G SDI FMC daughter
card) for multi-rate designs
Software
• Intel Quartus Prime (for hardware testing)
• ModelSim* - Intel FPGA Edition, ModelSim-SE, NCSim (Verilog only), Riviera-Pro,
or VCS (Verilog only)/VCS-MX simulator
1.3 Generating the Design
Use the SDI II parameter editor in the Quartus Prime software to generate the design
examples.

Example Design
1. Create a project targeting Arria 10 device family and select the desired device.
2. In the IP Catalog, locate and double-click SDI II IP Core. The New IP Variant
or New IP Variation window appears.
3. Specify a top-level name for your custom IP variation. The parameter editor saves
the IP variation settings in a file named <your_ip>.ip or <your_ip>.qsys.
4. Click OK. The parameter editor appears.
5. On the IP tab, select your desired IP settings. The generated design example will
be based on your settings.
6. On the Design Example tab, select Simulation to generate the testbench, and
select Synthesis to generate the hardware design example.
You must select at least one of these options to generate the design example files.
7. For Generate File Format, select Verilog or VHDL.
8. For Target Development Kit, select Arria 10 GX FPGA Development Kit. You
may change the target device using the Change Target Device parameter if your
board revision does not match the grade of the default targeted device.
9. Click Generate Example Design.

1.4 Simulating the Design
The SDI II design example testbench simulates one channel serial loopback design
with TX instance connected to an internal video pattern generator. The serial output
from the TX instance connects to the RX instance in the testbench. The testbench also
includes checkers and control mechanisms.

Results
1. Navigate to the simulation folder of your choice.
2. Run the simulation script for the supported simulator of your choice. The script
compiles and runs the testbench in the simulator.
3. Analyze the results.

To compile and run a demonstration test on the hardware design example, follow
these steps:
1. Ensure that the hardware design example generation is complete.
2. Open quartus/sdi_ii_a10_demo.qpf.
3. Click Processing ➤ Start Compilation.
4. If you turn on the Dynamic Tx clock switching parameter in the Design
Example parameter editor, set the frequency for CLK2 or CLK3 in the Si5338
(U14) tab of the Clock Control GUI.
• For HD/3G-SDI single-rate and triple-rate designs, set CLK3 to 148.3516 MHz.
• For multi-rate designs, set CLK2 to 296.7033 MHz.
5. After successful compilation, the Quartus Prime software generates a .sof file in
your specified directory.
6. Configure the selected Arria 10 device on the development board using the
generated .sof file (Tools ➤ Programmer ).
7. For serial loopback designs, open the System Console to control the internal video
pattern generator. Click Tools ➤ System Debugging Tools ➤ System Console.
Note: Close the Clock Control GUI and the Programmer window before you open
the System Console.
8. After the initialization, type source ../hwtest/tpg_ctrl.tcl in the System
Console to open the pattern generator control user interface. Select your desired
video format.

1.5.1 Connection and Settings Guidelines
Before programing with the .sof file, ensure that the connections and settings are
correct.
Connections and Settings for HD/3G-SDI Single Rate and Triple Rate Designs
• For parallel loopback design, the on-board SMB RX connector (J20) connects to an
external video source and the on-board SMB TX connector (J21) connects to a
video analyzer.
• For serial loopback design, the on-board SMB TX connector (J21) connects to an
on-board SMB RX connector (J20) or a video analyzer.
• Ensure all switches on the development board are in default position.
• The SDI video analyzer displays the video generated from the source.
Note: For parallel loopback designs, you may need to switch the Si516_FS
(SW6.3) at the back of the board if you are switching between fractional
frame rate and integer frame rate video format.
