Syntax

mapPort(dut,dutPorts)

Description

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

The generated setup function file contains the code required to configure your fpga object with the interfaces you configured for your DUT subsystem in Simulink®. For more information, see Run and Verify Hardware Implementation.

This example uses:

Open Live Script

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

collapse all

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

DUT ports, specified as an hdlcoder.DUTPort 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.
