AXI Verification Components, OSVVM vs UVVM

General questions

The UVVM provides the following VC for AXI: AXI4 Master/Slave, AXI4-Lite Master/Slave and AXI-Stream Source/Sink. Coincidently, OSVVM also provides VC for these busses.

I have the following questions:

  1. Do the UVVM VC for these AMBA busses support all parts of the specification for these busses?
  2. What is the difference between the UVVM VC for these busses and the ones from OSVVM?
