Chapter 8

Developing Applications for the High-Speed Serial Device

•

The Xilinx Vivado tools create a blank project, from which you can develop socketed CLIP. 
For more information about using the Xilinx Vivado tools to develop socketed CLIP, refer 
to the 

Accessing the Xilinx Vivado Tools

 section.

•

You can also design your project in LabVIEW, then export the project to the Vivado Design 
Suite. For more information about exporting a LabVIEW FPGA VI as a Vivado Design 
Suite project, refer to the 

Exporting to Vivado

 section. 

Accessing the Xilinx Vivado Tools

Complete the following steps to run Xilinx Vivado and generate a blank project for CLIP 
development.
1.

Ensure that your system meets the system requirements listed in the 

NI High-Speed Serial 

Instruments Readme

, available from the Start menu and at 

ni.com/manuals

. You can 

check the versions of the tool on your machine by selecting 

Start»Control Panel»

Programs and Features

.

Note

If Vivado is installed by LabVIEW FPGA, it does not appear in 

Programs 

and Features

.

2.

Open the Xilinx Vivado Tool directory by navigating to 

C:\NIFPGA\programs\

VivadoXXXX_Y

, where 

XXXX

 and 

Y

 refer to the Xilinx Vivado tool versions. For 

example, <VIVADO_DIR> version 2013.4 is located at 

C:\NIFPGA\programs\

Vivado2013_4

.

3.

Run the Xilinx Vivado batch file: 

<XilinxVivadoDir>\bin\vivado.bat

.

You may receive the following warning when launching Vivado.

Figure 8-2.  

EDK Environment Error Message

This error message is expected. You can ignore the error message if you are not using the 
Xilinx Embedded Development Kit (EDK). The EDK is not required for development with 
the high-speed serial device.

4.

Click 

New Project

 and follow the instructions in the wizard.

You can also export an FPGA VI as a Vivado Design Suite project, as detailed in the 

Exporting 

to Vivado

 section.
