release

Release the hardware resources associated with fpga object

Since R2024a

Add-On Required: This feature requires the Wireless Testbench™ Support Package for NI™ USRP™ Radios add-on.

Syntax

release(dut)

Description

release(dut) releases the hardware resources associated with the fpga object dut.

Examples

Access DUT, Map RFNoC Register Interface, and Read Data

Create a usrp System object, specifying a radio setup configuration previously saved in the Radio Setup wizard.

device = usrp("MyRadio");

Configure your radio with the target interfaces.

describeFPGA(device,"ModelName_wthandoffinfo.mat"); 

Create an fpga object to access your DUT on the FPGA of your radio.

dut = fpga(device);

Add an RFNoC register interface to your DUT.

addRFNoCRegisterInterface(dut, ...
    "InterfaceID","DUTName", ...
    "RFNoCBlock","0/DUTName#0");

Create an hdlcoder.DUTPort (HDL Coder) object for the DUT port and specify the properties.

DUTPort_Read_Register = hdlcoder.DUTPort("Read_Register", ...
	"Direction","OUT", ...
	"DataType","int16", ...
	"IsComplex",false, ...
	"Dimension",[1 1], ...
	"IOInterface","DUTName", ...
	"IOInterfaceMapping",1);

Map the DUT port to the RFNoC interface you added to your DUT.

mapPort(dut,DUTPort_Read_Register);

Connect to the radio and apply radio front end properties.

setup(device);

Read data from the DUT port.

data = readPort(dut,"Read_Register")

data = int16
    0

Release the hardware resources.

release(dut);

Input Arguments

dut — Target DUT on FPGA of target NI™ USRP™ radio device
