Sim86
Simulates MCUs with instruction accuracy, runs unmodified firmware, injects faults, and supports cloud-based parallel testing.
A high-fidelity MCU simulator that runs unmodified firmware on virtual hardware, enabling engineers to test and debug embedded systems before physical boards are available. It targets embedded software developers and engineering teams in mid-market and enterprise companies. The platform is delivered as a SaaS with a web IDE, SDK for automation, and MCP integration for coding agents, distinguishing itself through instruction-accurate emulation and fault injection.
