shippingGroup Ethernet / NetworkingStandard IEEE 802.3bz (2.5GBASE-T) — MAC-frame + MDIO layer only

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 identical MAC-frame+MDIO deliverable with vip-eth-1gbaset: an independent, clean-room Ethernet frame BFM and Clause-22 MDIO PHY-model BFM exercising the catalog’s real Gigabit-class gmac at the protocol layer, which is common to both the 1G and 2.5G rate points (the byte-stream MAC interface gmac exposes is PHY-speed-independent — the PHY adapter below it, not this MAC, is where 1G vs 2.5G actually differs). Covers preamble/SFD/FCS-framed TX and RX frame injection/capture plus a full MDIO read/write round trip against an independent PHY register model, with a passive checker independently re-verifying frame/FCS legality. The 2.5GBASE-T-specific PHY layer (PAM16 signaling, speed down-shift/auto-negotiation sequencing) and the AXI4-Lite DMA descriptor path are not exercised by this first-pass MAC-level VIP.

Key Features

Independent Ethernet frame BFM + Clause-22 MDIO PHY-model BFM — same deliverable as vip-eth-1gbaset, since both share gmac‘s PHY-speed-independent MAC-frame layer
MAC frame-layer (preamble/SFD/FCS) TX capture and RX injection verified against the real GMAC, independently CRC-32-checked
MDIO register read/write round-trip verified through the DUT’s own Clause-22 controller against an independent PHY register model
Roadmap, not yet covered: 2.5GBASE-T PAM16 signaling / speed down-shift auto-negotiation, and the AXI4-Lite TX/RX-DMA descriptor path

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.
