Available now — real, tested verification collateral, not a roadmap placeholder.

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 you get

Bus-functional model

An independent driver for the protocol, written clean-room from the public specification — not derived from our own RTL, so it is a genuine second source.

Passive protocol checker

A monitor that watches the bus and asserts the spec’s rules continuously, so a violation fails the run where it happens rather than downstream.

Self-checking interop testbench

A one-command testbench that drives the model against real RTL and hard-checks the result — reproduce every claim on day one.

Shares the exact same deliverable as vip-usb2 against the same catalog usb2_dev RTL, since that RTL is confirmed — by reading its ULPI FSM, register map, and reset-time OTG_CTRL write — to be a fixed-role, device-only USB 2.0 Full-Speed link controller: it implements no host-mode ULPI signaling and no SRP/HNP state machine; the one “OTG_CTRL” register write at boot only configures the device-mode D+ pull-up, not a dual-role capability. This VIP therefore validates exactly the device-side link-layer packet exchange described in vip-usb2 and explicitly does NOT cover OTG role-swap, HNP (Host Negotiation Protocol), or SRP (Session Request Protocol) negotiation — because the underlying RTL has no host or dual-role path for this VIP to exercise, not merely because this VIP chose not to build one.

Key Features

Identical deliverable to vip-usb2 (same BFM/checker/TB files) against the same usb2_dev RTL
Confirmed by reading the RTL: usb2_dev implements no host-mode ULPI signaling and no SRP/HNP state machine — its OTG_CTRL boot-time register write only configures the device-mode D+ pull-up
OTG role-swap / Host Negotiation Protocol / Session Request Protocol negotiation is explicitly NOT covered — not a scoping choice by this VIP, but because the RTL itself has no host or dual-role path to verify
Roadmap: genuine SRP/HNP verification is gated on usb2_dev (or a future OTG-capable sibling IP) first implementing host-mode/dual-role logic

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.
