Agentic HIL
An open-source framework that combines Hardware-in-the-Loop (HIL) testing concepts with AI coding agents, enabling those agents to develop firmware directly targeting real hardware. Successful test execution on a physical target board serves as the acceptance gate for code changes.
Timeline (last 90 days)
Agentic HIL is an open-source framework licensed under Apache-2.0, with the goal of enabling programming agents to develop firmware directly targeting real hardware.
Agentic HIL acts as a hard gate in the development process, accepting code changes only when all specified tests pass on the physical target board.
The Agentic HIL development cycle is: write code, compile and build, flash to the board, run tests, read board responses, analyze failure causes, and iterate with modifications—all driven autonomously by the agent.
In Agentic HIL, developers are responsible for defining requirements, hardware permissions, and acceptance tests, while the agent is responsible for executing the complete development cycle within those boundaries.
The hardware permission mechanism can restrict the agent's access to specific peripherals, pins, or operations, preventing AI from performing destructive or unsafe operations on physical devices.
Agentic HIL provides a reproducible starter example with a deliberately planted firmware bug, allowing users to experience how the agent discovers and fixes it.
The Agentic HIL project is currently maintained by a single person and is in an early stage seeking community feedback.
Real hardware-in-the-loop testing cannot be parallelized infinitely like pure software, and test throughput is limited by the number of physical boards available.
Each round of iteration between the agent and the hardware has actual time costs (flashing, running, reading responses), and the physical time overhead is far greater than that of software unit tests.
The maintainer introduced the Agentic HIL project on Reddit and sought community feedback.
