mapPort

Map a DUT port to an RFNoC interface

Since R2024a

Syntax

mapPort(dut,dutPorts)

Description

mapPort(dut,dutPorts) maps DUT ports dutPorts to RFNoC interfaces in the DUT 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 a 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);

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 the FPGA of a target NI™ USRP™ radio device

fpga object

Target DUT on the FPGA of a target NI USRP radio device, specified as an fpga object.

dutPorts — DUT ports

hdlcoder.DUTPort object array

DUT ports, specified as a hdlcoder.DUTPort (HDL Coder) object array. This object array includes the name and a description of each DUT port, for example the direction and data type of the port.
