🚗 WIA-AUTO-009: Vehicle Semiconductor Standard

The WIA-AUTO-009 standard defines the specifications, classifications, and requirements for automotive-grade semiconductor components used in modern vehicles. This includes microcontrollers (MCU), system-on-chip (SoC), power management ICs, sensor ICs, and AI/ML accelerators designed to meet stringent automotive safety and reliability standards.

Scope: Automotive Grade Classifications: AEC-Q100/Q101/Q200 qualification standards · MCU & SoC Architecture: High-performance computing for vehicle control systems · Power Management: Efficient power delivery and battery management ICs · Sensor Integration: Temperature, pressure, current, and position sensing · AI/ML Accelerators: Neural processing units for autonomous driving · Functional Safety: ISO 26262 compliance with ASIL ratings

Generate a Phase 1 envelope

This simulator demonstrates the canonical envelope shape defined in the standard's Phase 1 specification. Click the button below to generate a sample envelope; the output is a JSON document that conforming implementations can verify with the reference CLI.

Press “Generate envelope” to produce a Phase 1 sample.

How envelope verification works

Every envelope in this standard is signed with Ed25519 over the canonical JSON form (RFC 8785 JCS). The signature covers all fields except the signature itself; downstream consumers verify by re-canonicalising and re-checking the Ed25519 signature against the publisher's tenant key registered in the WIA-OMNI-API trust fabric.

# Reference verification flow (pseudocode)
canon = jcs_canonicalise(envelope_without_signature)
ok    = ed25519_verify(publisher_pubkey, canon, envelope.signature.value)
assert ok, "envelope signature does not verify"

About this simulator

This page is a Phase 1 envelope simulator for the WIA-AUTO-009 standard. It is intentionally minimal: a working demonstration of the envelope shape, not a production implementation. Production implementations carry signing keys in the WIA-OMNI-API trust fabric, validate against the schema registry, and emit envelopes through the Phase 2 HTTP surface documented under ../api/.

The simulator is provided so that engineers evaluating the standard can see a concrete envelope without standing up a full publisher endpoint. The reference CLI under ../cli/ produces equivalent envelopes from the command line, which is the recommended path for any non-trivial experimentation.

For deeper context, the eBook companion volumes describe the domain rationale for each envelope field. Field choices in this standard are not arbitrary: each field exists to answer a question that downstream auditors, regulators, or interoperability partners would otherwise have to derive from the publisher's narrative documentation.
