Default System Reference Design
The HDL Coder™ software can generate an IP core with an AXI4 or an AXI4-Lite interface.
You can integrate the HDL IP core into the
Default system is a basic reference design that
contains an ARM processor and the HDL IP core. HDL Coder generates the HDL DUT IP core, and
inserts it into the reference design. The processor acts as master, and the IP core acts
as slave. By accessing the generated registers via the AXI4-Lite interface, the
processor can read and write data to and from the IP core. You can tune the parameters
on the FPGA, or probe the results from the FPGA via the AXI4-Lite interface in the IP
core. To tune the parameters or probe results, use this reference design with
External mode in Simulink®.
To specify the
Default system as the target reference
IP Core Generationas target workflow. Open the HDL Workflow Advisor. In the Set Target Device and Synthesis Tool task, specify
IP Core Generationas the Target workflow.
Default systemas target reference design. In the Set Target Reference Design task, for Reference design, select
Default system. You can also specify whether the code generator inserts the AXI manager IP and the data capture IP for the JTAG or Ethernet connection into the reference design.
AXI manager and FPGA data capture in the HDL Workflow Advisor support programmable logic (PL) Ethernet only. The processing system (PS) Ethernet is not supported.
By default, the
Ethernetoption for the Insert AXI Manager (HDL Verifier required) and FPGA Data Capture (HDL Verifier required) parameters is available for the Artix®-7 35T Arty, Kintex®-7 KC705, and Virtex®-7 VC707 boards. To enable this option for other Xilinx® boards that have the Ethernet physical layer (PHY), manually add the Ethernet media access controller (MAC) Hub IP in the
plugin_boardfile using the
addEthernetMACInterfacemethod before you launch the HDL Workflow Advisor tool.
For an example of automatic insertion of the AXI manager IP for the JTAG connection into a reference design, see Use JTAG AXI Manager to Control HDL Coder Generated IP Core.
Go through the workflow to generate the HDL IP core, and integrate the IP core into
Default system reference design.
