AVIP for USB 3.1

The Cadence® Accelerated Verification IP (AVIP) enables design acceleration using the Cadence Palladium® Verification Computing Platform, and supports a variety of use modes to enable both validation of systems and subsystems, as well as more extensive protocol compliance verification of block- and IP-level designs.

The AVIP library for USB 3.2 Gen 2 (USB 3.1) is a ready-made, highly configurable Verification IP for the USB interface. It enables tests to be run in a pure simulation environment, with the Cadence Xcelium simulator, or in simulation acceleration with the Xcelium simulator and the Palladium platform.

Specification Support

The AVIP for USB 3.2 Gen 2 is based on the following specification:
