xHCI Verification IP

The xHCI Verification IP targets the following three vendors:
1. xHC Driver developers,
2. xHCI IP developers (the xHCI VIP act as xHCD and xHCI Monitor),
3. USB3 device developers(By using existing PL/LL with the xHCI).

The xHCI VIP minimize the complexity and efforts needed for above vendors. This VIP is a light weight VIP with easy plug-and-play interface so that there is no hit on the design time and the simulation time.
