VIP for USB4

The Cadence® Verification IP (VIP) for USB4 provides a highly capable verification solution for the USB4 protocol incorporating bus functional model (BFM) and integrated protocol checkers and coverage. It is based on the next-generation USB protocol architecture of USB4 specification. The VIP for USB4 enables multiple simultaneous data and display protocols and supports them to share the bandwidth over the bus. It supports the two-lane operation and up to 40Gbps speed.

The VIP for USB4 is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Protocol Features

The USB4 protocol features details are currently restricted to the members of the USB4 Working Group. Please contact your local account team or Moshik Rubin at mrubin@cadence.com for further details and follow-up.
