AXI4-VIP-env

Environment to easily use AXI4 VIP on your AXI design, using Xilinx Vivado tool.

Strengths:

• Easy replacement of DUT in environment
• Verification of AXI4 Master IP

Weaknesses:

• Currently only supports AXI Master Verification

System Requirements

• Xilinx Vivado 2019.2
• make

Setup

1. Clone this github.

$ git clone [email protected]:TomasLAbreu/AXI4-VIP-env.git

2. Load settings for Vivado tool (which can be something like this):

source /tools/Xilinx/Vivado/2019.2/settings64.sh

The project is managed by a Makefile which calls the required scripts from scripts/. Run make help to generate list of targets with descriptions.

$ make help
run             Compile and simulate project
comp            Compile project
sim             Simulate project
update          Update constants, vlog.prj and protoinst files
clean           Clean working directory
help            Generate list of targets with descriptions

How to Use

1. Replace design in dut/
2. Run make update to generate rtl/constants.svh and update both scripts/vlog.prj and scripts/protoinst_files.
3. If needed, update rtl/constants.svh according to your AXI protocol constants
4. If needed, update rtl/axi_vip_wrapper.sv according to new DUT user ports
5. Update testbench sim/tb_axi_vip.sv
6. Compile and simulate the project

6.1. Build and simulate using the makefile:

$ make

6.2. Use Vivado tool to build the project and view the waveforms. To do that, launch Vivado and create project from tcl script. This can be done in several ways.

$ cd scripts/
$ vivado -mode tcl -source create_proj.tcl

Then, you can launch Vivado simulation. Start GUI to visualize simulation waveforms.

Vivado% launch_simulation
Vivado% start_gui

In the following times Vivado launches, after creating the Vivado project, create_proj.tcl is no more needed. To open the Vivado project, type:

$ vivado -mode tcl scripts/WORK/proj.xpr

Todo

• Add support for AXI VIP Master and Pass-Through
• Automatize axi_vip_wrapper.sv generation
• Allow for waveform visualization on Vivado after building project with make
