Chapter 8

Developing Applications for the High-Speed Serial Device

Using niInstr Streaming

The Streaming Instrument Design Library provides a consistent mechanism to handle both finite 
and continuous transfer streams. It provides stream monitoring and handshaking. It contains VIs 
for both the Host and FPGA.

Refer to the Aurora Simple Streaming sample project for an example of how to use the 
Streaming Instrument Design Library.

Using niInstr CLIP Adapters

The CLIP Adapters instrument design library includes AXI4-Lite and AXI4-Stream wrappers. 
Refer to the 

Connecting AXI4-Lite and AXI4-Stream Interfaces to the Host

 section of this 

chapter for more information about how to use the CLIP Adapters instrument design library.

Using niInstr Data Trigger

Use the Data Trigger Instrument Design Library VIs to generate a trigger when the input data 
sample is more than or less than the configured value.

This library supports multiple trigger types. For more information on supported triggers and 
their use, refer to the LabVIEW context help for the Data Trigger VIs.

This library supports various data types and samples per cycle.

Using niInstr Basic Elements

The Basic Elements Instrument Design Library contains VIs that perform common FPGA 
functions, such as detecting rising and falling edges, storing Boolean values, and data 
handshaking. Using this library can be beneficial when developing new FPGA logic for 
your instrument.

Using niInstr Eye Scan

Refer to the 

Connecting Signals to Enable Eye Scan

 and 

Debugging Link Connections Using Eye 

Scan

 sections of this chapter for information about using the Eye Scan instrument design library.

Connecting AXI4-Lite and AXI4-Stream Interfaces to 
the Host

In LabVIEW FPGA, the AXI4-Lite and AXI4-Stream wrappers are located on the 

<Target 

Name>\CLIP Adapters

 palette. 

These wrappers adapt a collection of CLIP I/O that implements AXI4-Lite protocol and 
signaling into a simple reader or writer endpoints that present 4-wire handshaking to the 
diagram. This handshaking allows easier transition to many FPGA features without the need 
to implement the state logic on your own.

NI provides the following wrappers:
