5Tech Silicon Emulator

A layered firmware-emulation engine for selected CPU architectures, microcontrollers, SoCs and boards, with deterministic scenarios and replayable evidence.

In development · selected targets

Run selected firmware workloads in an explicitly scoped virtual target. The engine separates CPU, peripheral, SoC and board models so the supported behavior and remaining gaps stay visible.

See the tools in action

Watch six recorded workflows across Simulator Studio and Silicon Emulator, from firmware execution to connected-device tests.

Recorded development-build examples, edited in November 2026. Model and backend limits are shown in the video; these examples do not establish universal hardware support or real-time qualification.

Firmware and Linux: Real QEMU, Renode and Silicon backends run as separate nodes. This is not cycle-coherent co-simulation.
Sensor and ADC bench: Explore a live sensing chain. Refrigeration, transport and physical hardware are not modeled.
Circuit-to-MQTT alarm: Solved bench circuits feed real Mosquitto MQTT messages. The example is not a physical power-grid or battery model.
Motor fault injection: Inject and clear a stall in behavioral MCU and motor models. Distance is estimated odometry, not GPS.
BLE-to-MQTT workflow: Virtual BLE GATT exchanges use Bumble and real MQTT. No native ESP32 radio firmware or physical RF is demonstrated.
Linux guest telemetry: A real ARM64 guest receives telemetry through a host console relay. This case has no connected guest network interface.

What you can explore

Layered target models

Selected CPU, microcontroller, SoC and board models with per-target capability reporting.

Repeatable execution

Deterministic scenario execution, stimulus and replay help investigate a specific behavior and reproduce a result.

Integration interfaces

Time-master JSON, a C interface and FMI 2.0 FMU support provide boundaries for connected simulation workflows. Available ports vary by target.

Source-bound evidence

Selected original vendor firmware examples have retained execution reports, including a scoped STM32F407 DMA example. Evidence is tied to the tested workload and revision.

Scope & current limits

Soft pacing and measured 1× operation exist for selected workloads and host configurations. This is not a hard-real-time guarantee.
Model-to-model serial, GPIO, CAN, I2C, SPI, USB and Ethernet support varies by target; it is not a blanket compatibility claim.
Physical-I/O admission tests use a test transport. Real hardware drivers are not generally qualified.
A passed example does not qualify a whole chip, SDK, analogue model or production system. Physical validation remains necessary.

Planned capabilities

Broader device, peripheral and firmware coverage with explicit qualification evidence.
Additional Studio-managed hardware connections and AI-assisted analysis, subject to implementation and validation.
