1. A method to be used with a simulator and a controller, the controller for running execution code to provide output signals which, when linked to manufacturing tools, cause the manufacturing tools to cycle through requested activities, the simulator for receiving controller output signals and, in response thereto, generating motion pictures of manufacturing tools as the manufacturing tools cycle through requested activities, the simulator using data structures which model the manufacturing tools to determine which motion pictures to generate, the method for generating execution code and data structures for use by the controller and the simulator, respectively, and comprising the steps of:

  • for each manufacturing tool, encapsulating manufacturing tool information including manufacturing tool logic in a control assembly (CA);

    instantiating at least one instance of at least one CA;

    compiling instantiated CA instance manufacturing tool logic to generate execution code for controlling manufacturing tools;

    gleaning simulation information from the instantiated CA instances; and

    using the gleaned simulation information to generate a simulation data structure for the manufacturing tools corresponding to the instantiated CA instances.
