AXI4 Verification Component Library

The AXI Verification Component Library implements verification components for:

• AXI4
  • Manager with bursting
  • Memory Subordinate with bursting
  • Transaction Subordinate - no bursting
• AXI4 Lite
  • Manager
  • Memory Subordinate
  • Transaction Subordinate
• AXI Stream
  • 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.

Learning OSVVM

You can find an overview of OSVVM at osvvm.github.io. Alternately you can find our pdf documentation at OSVVM Documentation Repository.

You can also learn OSVVM by taking the class, Advanced VHDL Verification and Testbenches - OSVVM™ BootCamp

Download OSVVM Libraries

OSVVM is available as either a git repository OsvvmLibraries or zip file from osvvm.org Downloads Page.

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.

Participating and Project Organization

The OSVVM project welcomes your participation with either issue reports or pull requests.
