Configuring MGT Socketed CLIP in the NI-793xR
LabVIEW FPGA Targets

Complete the following steps to configure MGT Socketed CLIP in your NI-793xR LabVIEW
project:

1.

Create a new project by selecting

File»New»Project

, or open an existing project by

selecting

File»Open

.

2.

Right-click the project in the

Project Explorer

window and select

New»Targets and

Devices

from the shortcut menu to display the

Add Targets and Devices

dialog box.

3.

Select

New target or device

and select your device.

4.

Right-click the device in the

Project Explorer

window and select

New»FPGA Target

to

add an FPGA target to the Controller for FlexRIO.

5.

Add the protocol IP through your CLIP. Right-click the device name and select

Properties»Component-Level IP.

Note

If you are using example CLIP or pre-made CLIP, you can import the CLIP

using the dialog box, or you can click on the

Create File

icon to create a new CLIP

using the CLIP Wizard.

Note

You can modify a CLIP by selecting the preexisting CLIP Declaration Name

and clicking

Modify File

.

6.

If you are generating new CLIP, follow the instructions in the CLIP Wizard to interface
your CLIP with LabVIEW FPGA. You do not need to use the CLIP Wizard if you are
reusing an existing CLIP. Refer to the

FPGA Module Help

for more detailed information

about the CLIP Wizard. The CLIP Wizard guides you through the following tasks.

•

Adding VHDL source, XDC constraints, and EDF/EDN/EDIF netlists

•

Configuring device types

•

Configuring generics

•

Performing syntax checks

•

Specifying how to use the signals in your CLIP

Note

In Step 2 of the CLIP Wizard, select the appropriate Component Level IP

Type for your target.

Note

After you create the CLIP and add the files, you do not need to modify the

CLIP for any changes to take place if you do not change the source paths. If you
change the source paths or modify the CLIP source files, you must use the CLIP
Wizard.
