The deliverable

What you’re licensing

A synthesizable SystemVerilog MIPI DSI (Display Serial Interface) Host 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

A synthesizable SystemVerilog MIPI DSI (Display Serial Interface) Host Controller. Digital-only; it implements the DSI packet protocol layer and connects to an external MIPI D-PHY Tx hard macro via a parallel byte-data interface.

Key Features

Command mode: DCS short / long write
Video mode: packed RGB888 with blanking
MIPI Hamming(6,1) header ECC on every packet
CRC-16 on long-write / pixel-stream packets
8-entry command FIFO; APB4 slave; W1C interrupt

Getting Started

  // 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 instrument clusters, camera pipelines, and safety-monitored display paths.

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.
