Planned — scoped for this wave; deliverables not yet built. Ask if you need it sooner.

Verification IP is not safety-rated. These are testbench components — no ASIL target, no FMEDA, no IP-XACT, no safety-mechanism interface. They exist to help you verify a design, not to carry a safety argument. The safety soft-IP catalog is over here.

The deliverable

What is scoped

Scoped, not yet built

This VIP is specified against the protocol’s public standard and scheduled for the current wave. The deliverables below describe the intended shape, not shipped code.

Ask if you need it sooner

Scoping is done, so a concrete date is a conversation away. Customer demand reorders the wave.

Same shape when it lands

Every shipping VIP arrives as a clean-room bus-functional model, a passive protocol checker, and a self-checking interop testbench.

Multi-tier hub topology verification — downstream-port power/reset sequencing and upstream traffic aggregation across mixed-speed devices.

Key Features

Multi-tier, multi-port hub topology traffic aggregation
Per-port power-switching and over-current reporting
Mixed-speed downstream device negotiation (2.0/3.x/4 on the same hub)

Verification IP is testbench collateral and is deliberately not safety-rated: no ASIL target, no FMEDA, and no IP-XACT descriptor. It carries no functional-safety claim.
