release

R2026b

Release the hardware resources associated with fpga object

Since R2024a

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 by using the describeFPGA function.

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 by using the addRFNoCRegisterInterface function.

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

Create an hdlcoder.DUTPort 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);

Using the mapPort function, 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 by calling the setup function.

setup(device);

Read data from the DUT port by using the readPort function.

data = readPort(dut,"Read_Register")

data = int16

0

Release the hardware resources.

release(dut);

Input Arguments
