CARME
CARME · Peripherals
Preview650+ peripheral models. Register-exact, tested on real firmware.
Every model follows the register map and behaviour in its vendor's reference manual, and is tested with the firmware that drives it: vendor SDK examples, Zephyr drivers and Linux drivers. When a model is not enough, run the block's RTL in its place.

A world around the chip
Sensors that move, networks with something on the other side.
01
Sensors that move
A sensor model reads data, not just a register value: feed an IMU a recorded flight, a thermometer a temperature curve, a camera a video, a GNSS receiver a track. Tests replay the same data on every run.
02
Networks with a world on the other side
Connect an emulated Ethernet port to a host network, a CAN bus to a real CAN interface or a log file, a UART to a terminal, a socket or a test. A radio talks to every other emulated radio in range, with loss and latency you set.
Write your own
Registers in YAML, behaviour in Python.
Describe the registers in a .cmperiph and the behaviour in Python. It loads without rebuilding CARME. Or keep the register description and point it at your RTL instead.

Common questions.
How accurate are the models?
Each model follows the register map and behaviour in the vendor's reference manual, and is tested with the firmware that drives it. When you need more, run the block's RTL in its place.
A peripheral I use is missing.
Write it in Python from its register description, or ask us: we add models for test partners first.
