is a ready-to-execute test execution management software used to organize, control, and execute your automated prototyping, validation, or manufacturing test systems. Archon is the core software of a domestic test operating system.

Software Interface

Automatically discovers instruments, enabling simple control and management. Rich system APIs, including connection management APIs and test result judgment APIs, enhance development efficiency. Graphical drag-and-drop operations and auto-completion reduce development complexity. Test cases are saved using CVS and Python for easy editing and version management.

Supports two modes: distributed deployment, sequential execution, and parallel execution, flexibly adapting to various production test scenarios. Test data results can be stored in a database for visual analysis or exported and saved locally using custom templates.
