Shares the exact same MAC-level interop deliverable as vip-automotive-eth and vip-eth-10m.

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 MAC-level interop deliverable as vip-automotive-eth and vip-eth-10m. 100BASE-T1 is full-duplex point-to-point at the MAC level (the PLCA gate is bypassed entirely, per eth_t1_mac‘s own RTL), so the MAC frame/FCS correctness this deliverable proves is honestly the complete picture of the DUT’s role at this speed — there is no separate arbitration layer to additionally verify, unlike the 10M entry. PHY-level 100BASE-T1 PAM3 line coding and link training are below the verified interface and not covered.

Key Features

Shares eth_t1‘s independent frame BFM + checker + interop TB with vip-automotive-eth and vip-eth-10m — one MAC-level deliverable, PHY-speed-independent by design
Verifies the byte-stream MAC interface (framing, FCS, RX register reporting) that a 100BASE-T1 PHY sits behind
100BASE-T1 has no PLCA/arbitration layer at the MAC level (full-duplex, TX gate always open), so this deliverable’s MAC-layer proof is complete for this speed variant, not a partial one
Does NOT cover PHY-level 100BASE-T1 PAM3 line coding or auto-negotiation/link-training sequencing (below the MAC interface by design)

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.
