shippingGroup StorageStandard JEDEC JESD84-B51 (eMMC 5.1) — command/response + block-data 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 same clean-room SD command/response + single-block DAT-transfer deliverable as vip-sdio (CMD0/CMD8/CMD1 init, CMD17/CMD24 single-block read/write, independent CRC7/CRC16 checker) against the catalog’s sdmmc controller in its eMMC-compatible mode, since the CMD-line framing and DAT-line CRC16 block protocol are the same physical/electrical layer eMMC builds on. eMMC-specific features — boot/RPMB/GP partition addressing, Command Queuing, HS200/HS400 timing modes — are NOT exercised by this generic command-layer test and remain roadmap.

Key Features

Independent card BFM proves the eMMC-shared CMD/RESP + single-block DAT protocol end-to-end against the real sdmmc host controller
Passive protocol checker independently re-validates CRC7/CRC16/framing legality on the wire, plus a directed CRC16 injection test
Boot/User/GP-partition addressing and RPMB authenticated read/write are NOT modeled — roadmap
Command Queuing/Packed-Commands and HS200/HS400 (SDR/DDR + Enhanced Strobe) timing are NOT modeled — 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.
