Abstract

A method and apparatus for developing microcomputer-based systems. A controller model having at least one parameter is simulated and, similarly, a plant model having at least one parameter and controlled by the controller model is simulated. A user interface then has access to the parameters of the controller model and plant model and optionally suspends the execution of the controller model and plant model in response to a trigger event. The user interface determines the status of the controller model parameters and/or plant model parameters at the time of the trigger without altering the controller model parameters or plant model parameters or the program code of the controller model.
