Map DUT Ports in HDL IP Core to AXI4 Slave Interfaces
This example shows how to map the DUT ports in the HDL IP core to AXI4 slave interfaces.
Create an fpga
object with Xilinx
as
Vendor
.
hFPGA = fpga("Xilinx")
hFPGA = fpga with properties: Vendor: "Xilinx" Interfaces: [0x0 fpgaio.interface.InterfaceBase]
Add the AXI4 slave interface to the
hFPGA
object by using the addAXI4SlaveInterface
function.
%% AXI4 Slave addAXI4SlaveInterface(hFPGA, ... "InterfaceID", "AXI4-Lite", ... "BaseAddress", 0xA0000000, ... "AddressRange", 0x10000);
Specify the DUT ports in the HDL IP core as an hdlcoder.DUTPort
object array and then map the port to the AXI4 slave
interface.
hPort_h_in1 = hdlcoder.DUTPort("h_in1", ... "Direction", "IN", ... "DataType", numerictype(1,16,10), ... "Dimension", [1 1], ... "IOInterface", "AXI4-Lite", ... "IOInterfaceMapping", "0x100");
Map the DUT port objects to the AXI4 slave interface.
This information is saved as a property on the hFPGA
object.
mapPort(hFPGA, hPort_h_in1) hFPGA.Interfaces
ans = AXI4Slave with properties: InterfaceID: "AXI4-Lite" BaseAddress: "0xA0000000" AddressRange: "0x10000" WriteDriver: [1×1 fpgaio.driver.AXIMemoryMappedIIOWrite] ReadDriver: [1×1 fpgaio.driver.AXIMemoryMappedIIORead] InputPorts: "h_in1" OutputPorts: [0×0 string]
Map DUT Ports in HDL IP Core to AXI4-Stream Interfaces
This example shows how to map the DUT ports in the generated HDL IP core to AXI4-Stream interfaces.
Create an object for the target device.
hFPGA = fpga("Xilinx")
hFPGA = fpga with properties: Vendor: "Xilinx" Interfaces: [0x0 fpgaio.interface.InterfaceBase]
Add the AXI4-Stream interface to the hFPGA
object by using the
addAXI4StreamInterface
function.
%% AXI4-Stream addAXI4StreamInterface(hFPGA, ... "InterfaceID", "AXI4-Stream", ... "WriteEnable", true, ... "ReadEnable", true, ... "WriteFrameLength", 1024, ... "ReadFrameLength", 1024);
Specify the DUT port as an hdlcoder.DUTPort
object array and then
map the port to the AXI4-Stream interface.
hPort_x_in_data = hdlcoder.DUTPort("x_in_data", ... "Direction", "IN", ... "DataType", numerictype(1,16,10), ... "Dimension", [1 1], ... "IOInterface", "AXI4-Stream"); hPort_y_out_data = hdlcoder.DUTPort("y_out_data", ... "Direction", "OUT", ... "DataType", numerictype(1,32,20), ... "Dimension", [1 1], ... "IOInterface", "AXI4-Stream");
Map the DUT port objects to the AXI4-Stream interface. This information is saved as
a property on the hFPGA
object.
%% Map DUT port to AXI4 Slave driver
mapPort(hFPGA, [hPort_x_in_data, hPort_y_out_data]);
hFPGA.Interfaces
ans = AXI4Stream with properties: InterfaceID: "AXI4-Stream" WriteEnable: 1 ReadEnable: 1 WriteFrameLength: 1024 ReadFrameLength: 1024 WriteDriver: [1×1 fpgaio.driver.AXIStreamIIOWrite] ReadDriver: [1×1 fpgaio.driver.AXIStreamIIORead] InputPorts: "x_in_data" OutputPorts: "y_out_data"
Input Arguments
hFPGA
— Target FPGA object
fpga object
fpga
object for the target vendor, specified as an fpga
object.
hDUTPorts
— Object array of DUT ports
hdlcoder.DUTPort object
DUT port or ports that you want to map to an IP core interface. Each port is an
object array that you create by using the hdlcoder.DUTPort
function.
