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.

An independent I3C SDR controller and target pair, structured like the I2C VIP but with the protocol’s defining difference modeled correctly: a data byte’s 9th bit is the SDR T-bit (odd parity), not an I2C-style ACK. Same passive-checker and self-checking-interop-TB discipline as the I2C VIP, run directly against this catalog’s i3c_slave RTL including read-side T-bit parity and an injected-error detection case.

Key Features

Independent SDR controller and target — MIPI I3C SDR-private subset
9th-bit T-bit (odd parity) modeled correctly, not conflated with an I2C ACK
Passive protocol checker for SDR SDA/SCL data-validity and framing legality
Self-checking interop TB against the catalog’s i3c_slave: read T-bit parity + injected-error detection — all pass

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.
