Software emulator for hardware components in a gas delivery system of substrate processing system

Abstract:

A software emulation system for a gas delivery system of a substrate processing system includes an input/output bus and an emulator bus. An input/output bus adapter includes a switch configured to route data packets from a system controller for the substrate processing system to one of the input/output bus and the emulator bus. A gas delivery system emulator in communication with the emulator bus is configured to receive the data packets from the input/output bus adapter via the emulator bus and perform software-based emulation of a plurality of hardware components of the gas delivery system that are interconnected. The plurality of hardware components are modelled using one or more software models and include a gas source and at least one of a valve and a mass flow controller.
