UVVM - the new VHDL verification methodology is a very good way to structur
e your VHDL testbenches - and to make easily understandable, maintainable,  
extendible and reusable testbench architectures.

UVVM is free and open source, and now a whole set of BFMs and Verification  
Components are also available - open source and for free. This allows a ver
y fast kick-off for new users of UVVM, and of course a really good start fo
r any VHDL testbench development. They also serve as examples on how users  
can make their own BFMs and VVCs. In fact - if you have already made your B
FM procedures for your proprietary protocol - you can make a VVC for that i
nterface in 15 to 60 minutes.

Spend 5 minutes to read our post
'Advanced VHDL Verification - Made simple - For anyone'
e-espen-tallaksen?trk=mp-author-card, and see for your self how UVVM will
 allow far better and more structured testbenches to be implemented far fas
ter than before.

UVVM is free and open source, and you can use it for anything you like, wit
h no restrictions other than the standard MIT open source license.
UVVM is available from github.com  and  bitvis.no (released in February 201

Note that advanced randomization and coverage is available with UVVM via th
e included OSVVM or adapted UVVM-OSVVM.

Available BFMs and VVCs (VHDL Verification Components) are:
- AXI4-Lite
- Avalon-MM (Single access so far)
- SBI: Simple Bus Interface (Single cycle, optional ready - very simple bus
- I2C
- SPI (coming in June)
- GPIO (coming in June)

As UVVM takes off we expect the VHDL community will make more BFMs and VVCs
