The deliverable

What you’re licensing

arinc818 is an ARINC 818 (Avionics Digital Video Bus, ADVB / FC-AV) container controller, It is delivered as a licensable soft-IP block engineered as an ASIL-B Safety Element out of Context — not just RTL, but the complete functional-safety work package needed to carry it into an ISO 26262 program:

Synthesizable RTL

Portable, vendor-neutral SystemVerilog that drops onto your existing SoC fabric — no foundry or EDA-tool lock-in.

Per-IP FMEDA report

SPFM / LFM / PMHF computed against the ASIL target per ISO 26262-5 — the quantitative analysis your assessor asks for.

Safety manual

Assumptions of use, the safety mechanisms and their diagnostic coverage — written to drop straight into your safety case.

IP-XACT + integration docs

A machine-readable descriptor plus register and integration documentation for fast, low-risk bring-up.

Self-checking testbench

A self-checking (crypto: bit-exact) testbench and a one-command build, so you can reproduce every claim on day one.

What it is

arinc818 is an ARINC 818 (Avionics Digital Video Bus, ADVB / FC-AV) container controller, delivered as synthesizable SystemVerilog soft-IP on an APB4-lite slave with built-in ASIL-B safety instrumentation.

Key Features

ADVB container framing: Object-0 (container header) followed by Object-1 (active video) as a sequence of SOF..EOF FC-AV data frames, decoded from an external SerDes’s word+control token stream (rx_sof/rx_eof/rx_hdr/rx_data/rx_word)
Per-frame CRC-32 (IEEE-802.3 polynomial 0x04C11DB7) generate/check against the EOF word’s received CRC, plus SOF/EOF delimiter plausibility, folding into one protocol fault (err_code 3)
SEQ_CNT sequence-count tracking across the FC-AV data-frame run, flagged (err_code 3) on any break in the monotonic increment
Line/field counter checked against configured video geometry (LINES_PER_FRAME, OBJ0_WORDS/OBJ1_WORDS payload-word counts) — a wrong word count or runaway line count trips err_code 3
Free-running loss-of-video watchdog, re-armed on every SOF; exceeding the configured FRAME_TO with no new frame reports err_code 4
Built-in TX re-emit + loopback path replays the encoded token stream back into the RX FSM, self-checking the full container round trip (golden CRC-32 included) without an external SerDes
ASIL-B overlay: even-parity config-register protection (err_code 1) and KEEP_ATTR duplicate-DMR on the container/framing FSM plus line/SEQ_CNT counters (err_code 9), aggregated by a shared safety_monitor

Getting Started

// Minimal instantiation
arinc818 #(
  .ADDR_W(6)
) u_arinc818 (
  .clk       (clk),
  .rst_n     (rst_n),
  // APB4
  .p_paddr   (paddr),
  .p_psel    (psel),
  .p_penable (penable),
  .p_pwrite  (pwrite),

  .p_pready  (pready),
  // Safety
  .err_clear (1'b0),
  .err_valid (err_valid),
  .err_code  (err_code)
);

Configure via the CTRL register after reset to enable the IP and set operating parameters. Monitor err_valid / err_code for any safety faults reported by the built-in safety monitor.

Applications

Where it fits

Typically deployed in avionics, defense, and space systems built to the ARINC, MIL-STD, and CCSDS standards.

The case

Why license it, not build it

Skip 12–18 months

The FMEDA and the safety case are already generated. You integrate a finished safety element — you don’t stand up a safety-IP program to originate one.

One vendor, one safety story

Every block in the catalog shares the same safety architecture, fault-reaction model, and FMEDA methodology — so subsystems roll up cleanly.

Verified, not vapor

The RTL builds and passes today; the safety metrics come from analysis and fault injection against real RTL, not a datasheet promise.
