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 tsn_switch‘s descriptor-level forwarding VIP with vip-tsn: the queuing-and-forwarding slice specifically — per-frame egress-port selection (unicast/flood) and the single-outstanding-descriptor-per-port queue discipline the RTL implements, cross-checked by the same independent MAC-table checker. 802.1Qci per-stream filtering/policing and 802.1Qbu frame-preemption (this catalog entry’s original standards scope) are NOT modeled by tsn_switch, which has no filtering/preemption logic — genuinely roadmap, not exercised here.
Key Features
- Independent descriptor BFM + MAC-table checker exercise tsn_switch’s real forwarding/queuing datapath (same deliverable as vip-tsn)
- Cross-checks single-outstanding-per-port queue discipline (a fresh descriptor is never presented to a port that hasn’t drained) via the DUT’s own egr_valid/egr_ready handshake
- 802.1Qci per-stream filtering/policing is NOT modeled — tsn_switch has no per-stream filter/policer — roadmap
- 802.1Qbu frame preemption (express/preemptable queue interaction) is NOT modeled — tsn_switch has no preemption logic — roadmap

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.
