摘要:
A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not on time, but rather asynchronous discrete incidents known as events. A discrete event modeling environment can be used to model a control system using one or more discrete event-driven components. The event-driven components can be used to model certain portions of a control system that cannot be accurately modeled using a time-based model.

A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not directly on time, but rather aperiodic discrete incidents known as events. A discrete event modeling environment can be used to model a control system using one or more discrete event-driven components. The event-driven components can be used to model certain portions of a control system that cannot be accurately modeled using a time-based model.

In one embodiment, a method for displaying elements of an attribute in an executable block diagram model is provided. The method may include displaying an executable block diagram model in a first window and receiving a first input from an input device, wherein the first input associates with a first parameter of a block diagram modeling component in the executable block diagram model, the first parameter is represented in the executable block diagram model by a first graphical affordances. The method may include triggering the display of a value of a first parameter in a first user interface widget in the first window.

In an embodiment, a method of establishing directed relationships between states in a simulation is disclosed. The directed relationships may allow the simulation to proceed from an initial state according to two or more divergent behaviors. The simulation may merge if two or more behaviors result in states that are equivalent. The method may further allow a state of the simulation which has not been stored to be interpolated from one or more states that have been stored. In one embodiment, a system may receive a request to revert to a previous state, and the system may identify a saved state that is closest to the requested state. The system may simulate from the identified state to arrive at the requested state. In one embodiment, the simulation may be a hybrid simulation which is advanced in both discrete and continuous increments.

A Unified Debugger that enables the debugging of graphical models with combinations of entities from multiple domains such as time-based block diagrams, statecharts, and physical system models, with additional features for the debugging of hand-written and automatically generated code is disclosed. A view of the entity being executed that is consistent with the type of the modeling domain to which the entity currently being executed belongs is automatically generated for a user. Rather than requiring a user to manually transition from one debugger to the next, the Unified Debugger applies the appropriate debugging features from each modeling domain. The Unified Debugger also enables integration of diagnostic information from a multitude of modeling domains into a central user interface. In addition, a standard diagnostic interface which spans a plurality of modeling domains is defined that enables the customization of debug behavior.

A mechanism for constructing a software-based instrument panel or front panel in which the components correspond directly with sections of code in a textual language program is disclosed. The textual language program relates to how the panel updates and operates in a continuous fashion. Icons representing panel components are selected from a component library window displayed to a user. The act of dragging the icon representing the components into the Graphical Panel Layout Window automatically causes the corresponding code to be added to the textual language program and displayed to the user in a Program Dialog Window. The present invention displays both a Graphical Panel Layout Window showing the components in the instrument panel and a Program Dialog Window showing the lines of code for the textual language program controlling the operation of the components in the instrument panel. A library containing I/O dialog devices is also presented and displayed to a user. The selection by the user of an I/O device icon and the subsequent dragging of the icon into either the Graphical Panel Layout Window or the Program Dialog Window causes the associated lines of code to appear in the Program Dialog Window.
