  • DYNAMIC GENERATION OF FORMATTED USER INTERFACES IN SOFTWARE ENVIRONMENTS
    Publication number: 20120272213
    Abstract: Methods and systems for selecting multiple entities of a model or models to set or change data of the multiple entities together in a modeling environment are disclosed. When users create or edit a model or models, information on the entities of the model or models is provided to the users so that the users can select multiple entities in the model or models. On the selection of the multiple entities in the model or models, the modeling environment dynamically generates a user interface for the selected entities of the model or models for displaying, setting or changing data of the selected entities together. The user interface may display data of the selected entities that is not common to all of the selected entities in a different manner so that the users can identify common data of the selected entities.

  • Automated linearization analysis
    Patent number: 8296118
    Abstract: A method and apparatus automatically determines equilibrium operating conditions of a system model. The automated method enables users of block diagram models of dynamic systems to utilize simulation to define operating conditions for linearization. The automated method further allows users to generate operating conditions during simulation instead of explicitly specifying them by hand or using trim analysis. In accordance with one example, the method of generating a linear time invariant model includes providing a system model. A user specifies at least one event at which a linearization analysis should be performed. A simulation of the system model is executed. The electronic device automatically performs the linearization analysis upon occurrence of the at least one event as the simulation is running. Output results are generated of the linearization analysis to form the linear time invariant model.

  • Non-graphical model dependencies in graphical modeling environments
    Patent number: 8271936
    Abstract: Graphical programming or modeling environments, such as a block diagram environment, are disclosed in which dependencies that influence how a model executes are defined without altering the visual representation of the model. In the graphical modeling or programming environment, users create a model that describes how the system is to execute. The users can then augment the model with non-graphical dependencies that provide general execution goals or specific dependencies between blocks. The user can augment the graphical model with dependency constraints specifying how the model should execute. The constraints are coupled to the model and can be optionally displayed on the model in a debugging/analysis mode to provide further insight into how the model executes.
