silicon-centric / HIL — hardware-in-the-loop test platform

Modular Hardware-in-the-Loop
Test Platform.

Drop your DUT onto the matching platform adapter, point the IV&V framework at it, and run a full regression suite before lunch. Built on Kria K26 — same Yocto BSP, same engineers, same evidence trail.

01 — Real silicon. Real signals.

First test in minutes, not weeks. On real silicon.

No vendor lock-in. No proprietary RTOS. No unfamiliar toolchain. The SoCcentric HIL is built on the same Kria K26 SoM, the same Yocto BSP, and the same IV&V framework already running in your program. Your engineers already know the stack.

The HIL is the seventh SoCcentric platform — a slot-based chassis with a fixed brain card, swappable platform adapter boards, and an extension-card catalog. Every interface beyond the common-denominator base is a card you choose.

Real silicon, not simulation

Your DUT runs its real firmware against real electrical signals. No SPICE model, no emulation layer, no "it works in sim" surprises on first board-bring-up.

Native IV&V integration

The HIL is a peripheral of the IV&V platform, not a separate tool. Test orchestration, evidence database, and Web UI carry forward unchanged.

Calibrated and audit-ready

Every measurement channel is calibrated and traceable. Certification mode — with signed, timestamped, requirement-mapped reports — is standard, not an upgrade.

02 — Architecture

One chassis. Any DUT. Every signal.

Three layers: the K26 brain card (APU running Yocto + IV&V, RPU running FreeRTOS watchdog, PL hosting FPGA I/O soft-IP), the slot backplane (six card slots sharing a high-speed HIL-Bus), and the platform adapter (DUT-specific connector and power conditioning). Swap the adapter to change the DUT. Swap the extension cards to change the interfaces.

K26 brain card

APU runs Yocto + IV&V framework; RPU runs FreeRTOS watchdog; PL hosts FPGA I/O and timing soft-IP

02
Platform adapter

DUT-specific PCB — connector, power conditioning, and signal translation. One adapter per SoCcentric platform

03
Extension cards

Slot cards for DIO, AIO, CAN/CAN-FD, Ethernet bus, motor/encoder, and more — chosen for each program

04
IV&V platform

The HIL connects to the IV&V server over gRPC and PTP — same test orchestration, same evidence database, same Web UI

03 — Hardware tiers

Three chassis tiers. One architecture.

HIL-Bench for desk-side bring-up, HIL-Rack for overnight CI regression, HIL-Cert for certification-grade evidence. Each tier shares the same K26 brain card, the same Yocto BSP, and the same IV&V integration. Fault injection — GPIO stuck faults, CAN bit errors, brown-out sweeps — runs as a campaign across all three tiers.

HIL-Bench

TIER 01 / BENCH

Four-slot desktop chassis for firmware bring-up at the engineer's desk. Plug in the DUT, open a browser to the Web UI, run a smoke test, and have results in under five minutes from power-on.

e.g., GPIO walk and CAN loopback on first board-spin

HIL-Rack

TIER 02 / RACK

Six-slot 2U rackmount chassis for headless CI regression. Triggered by a Git push, results posted as JUnit XML to the IV&V dashboard. Failed runs include captured waveforms, bus traces, and console logs as artifacts.

e.g., overnight regression suite on real silicon

HIL-Cert

TIER 03 / CERT

Eight-slot 3U chassis with calibrated measurement channels, PTP time sync, and signed evidence output. The certification regression pack produces a traceable report mapping each test to its requirement, including calibration provenance for every measurement channel.

e.g., ISO 26262 ASIL-B compliance evidence run

Fault Injection

MODE 04 / FAULT

Deterministic fault injection campaign across all tiers. Stuck-high GPIO, CAN bit errors mid-frame, brown-out at varying voltages, sensor signal clipping — each fault scripted, injected, and scored against expected DUT behavior.

e.g., brown-out sweep at 3.3 V ± 15%
04 — Slot cards

Six card slots. Every interface your DUT needs.

The HIL-Bus backplane connects the K26 brain card to up to six slot cards. The base set covers the common-denominator interfaces. Add extension cards for the protocols and signals your specific program requires. One chassis, any DUT class.

DIO Card

01 / DIGITAL I/O

Programmable digital I/O card for GPIO walk, edge capture, and PWM generation. Fault injection capable — individually pullable to stuck-high, stuck-low, or floating. Used for every DUT bring-up smoke test.

05 — What the HIL does

Five test disciplines. Hardware-up.

From pin-level GPIO validation to rest-of-bus emulation, fault injection to plant-in-the-loop motor control. Every discipline produces the same calibrated, traceable evidence trail — ready for your IV&V dashboard and certification submission.

Firmware bring-up

GPIO walk, peripheral smoke test, console capture, and boot-time health check. Engineer plugs in the DUT, opens the Web UI, and has a pass/fail result in under five minutes. Every signal state logged with FPGA edge timestamps.

Bus emulation

CAN-FD, EtherCAT, PROFINET, and SPI bus emulation with up to 12 virtual nodes per channel. The DUT believes it is in the real vehicle, machine, or network. Bus traffic captured with Wireshark-compatible pcap for post-run analysis.

Fault injection

Stuck-high GPIO, CAN bit errors mid-frame, brown-out at programmable voltages, sensor signal clipping. Each fault injected deterministically by the FPGA, DUT response captured, scored against expected behavior, and persisted in the evidence database.

Synthetic sensor injection

Programmable analog waveforms on calibrated DAC channels for ADC validation and sensor emulation. IMU, pressure, temperature, and encoder signals synthesized to spec. Deterministic timestamping aligned to the rest of the simulated environment.

Certification evidence

Calibration provenance on every measurement channel. Signed, timestamped, requirement-mapped test reports. Append-only evidence database — every run, every parameter, every result. ISO 26262, DO-178C, IEC 62304, and IEC 61508 artifact shapes supported.
