USB VIP

USB VIP (Universal Serial Bus VIP)
The USB VIP (Device and Host) is a highly flexible and configurable verification IP that can be easily integrated into any SOC verification environment. Supporting OVM and UVM, this USB VIP is part of the asureVIP portfolio of implementation-proven VIP offerings.

The USB VIP supports both USB 3.0 and USB 2.0 functionalities and has been entirely programmed in System Verilog and provides support for OVM and UVM based testbenches. The VIP comes with a protocol Bus Monitor which checks for non-compliance with USB 3.0/2.0 protocol violations, reported by monitors connected to PIPE and UTMI.

Customers using the asureVIP products do so with the confidence of knowing that they have been independently developed by T&VS and successfully deployed by leading SoC companies around the world.

T&VS can also offer asureVIP customers an independent hardware verification service (asureVERIF) that not only reduces development costs and time-to-to-market, but also improves product quality.
