MATLAB AXI Master

Access AXI slave memory on FPGA board from MATLAB^®

Access on-board memory locations from MATLAB, using the MATLAB AXI Master IP in your FPGA design, and the aximaster object. The object connects to the IP over the JTAG cable, and allows read and write commands to slave memory locations from the MATLAB command line.

Functions

`setupAXIMasterForVivado`	Add AXI master IP path to Vivado project
`readmemory`	Read data out of AXI4 memory-mapped slaves
`writememory`	Write data to AXI4 memory-mapped slaves
`release`	Release JTAG cable resource

Objects

aximaster Read and write memory locations on an FPGA board from MATLAB

Access FPGA External Memory Using MATLAB as AXI Master

Use MATLAB as AXI Master to access the external DDR memories connected to the FPGA. In the FPGA, there is a Xilinx DDR memory controller instantiated for accessing the DDR memories. This memory controller provides an AXI4 slave interface for read and write operations by other components in the FPGA. The MATLAB as AXI Master feature provides an AXI master component that can be used to access any AXI slave IPs in the FPGA. In this example, we demonstrate how to integrate this AXI master into a Xilinx Vivado project, and read/write to the DDR memory using MATLAB.

IP Core Generation Workflow without an Embedded ARM Processor: Xilinx Kintex-7 KC705

Use the HDL Coder™ IP Core Generation Workflow to develop reference designs for Xilinx® parts without an embedded ARM® processor present, but which still utilize the HDL Coder™ generated AXI interface to control the DUT. This example will use MATLAB as AXI Master IP from HDL Verifier™ and Xilinx JTAG Master to access the HDL Coder™ generated DUT registers. For the MATLAB as AXI Master, you can access DUT registers from MATLAB directly. For the Xilinx JTAG Master, you can access the DUT registers using Vivado Tcl Console by writing Tcl commands. The FPGA design is implemented on the Xilinx Kintex-7 KC705 board.
