OSVVM Common Library

The OSVVM Common library defines

• OSVVM Model Independent Transactions (MIT)
• Support functions for filling burst transfer FIFOs (in MIT or not)
• Generic Interrupt handler for MIT
• Model Parameter Settings support

About OSVVM's Model Independent Transactions (MIT).

MIT defines a common communication interface (record based) and transaction API for Address Bus and Streaming Interface. Using MIT makes verification component development as easy as any "Lite" approach to verification. Going further using a common transaction API simplifies the test development process.

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.
