# AXI4 Verification Component Library

The AXI Verification Component Library implements

verification components for:  

  - [AXI4](https://github.com/osvvm/AXI4#readme)

    - Manager with bursting

    - Memory Subordinate with bursting

    - Transaction Subordinate - no bursting

  - [AXI4 Lite](https://github.com/osvvm/AXI4#readme)

    - Manager

    - Memory Subordinate

    - Transaction Subordinate 

  - [AXI Stream](https://github.com/osvvm/AXI4#readme)

    - Transmitter

    - Receiver



## Testbenches are Included 

Testbenches are in the Git repository, so you can 

run a simulation and see a live example 

of how to use the models.

## Release History

For the release history see, [CHANGELOG.md](CHANGELOG.md)



## Learning OSVVM

You can find an overview of OSVVM at [osvvm.github.io](https://osvvm.github.io).

Alternately you can find our pdf documentation at 

[OSVVM Documentation Repository](https://github.com/OSVVM/Documentation#readme).



You can also learn OSVVM by taking the class, [Advanced VHDL Verification and Testbenches - OSVVM™ BootCamp](https://synthworks.com/vhdl_testbench_verification.htm)



## Download OSVVM Libraries

OSVVM is available as either a git repository 

[OsvvmLibraries](https://github.com/osvvm/OsvvmLibraries) 

or zip file from [osvvm.org Downloads Page](https://osvvm.org/downloads).



On GitHub, all OSVVM libraries are a submodule of the repository OsvvmLibraries. Download all OSVVM libraries using git clone with the “–recursive” flag: 

```    

  $ git clone --recursive https://github.com/osvvm/OsvvmLibraries

```

        

## Run The Demos

A great way to get oriented with OSVVM is to run the demos.

For directions on running the demos, see [OSVVM Scripts](https://github.com/osvvm/OSVVM-Scripts#readme).



## Participating and Project Organization 

The OSVVM project welcomes your participation with either 

issue reports or pull requests.
