A Discrete Event System model created or provided in a time domain modeling and simulation environment and/or an event domain modeling and simulation environment may be divided into multiple independent regions, e.g. 'subgraphs', to achieve interleaved execution of the components from different domains. The subgraphs are automatically identified by the modeling and simulation environment during the compilation. Each subgraph consists of one or more interconnected event-driven components. Each subgraph is associated with an event calendar that controls the execution of the associated subgraph. Such multiple event calendar design enables multi-domain simulation, where event-driven components modeled by an event domain modeling environment and time-driven components modeled by a time domain modeling environment are simulated in an integrated fashion.

Identification and simulation of multiple subgraphs in multi-domain graphical modeling environment

A device receives a dynamic system model for a graphical modeling environment, and associates an entity with the dynamic system model, the entity including an entity model. The device defines at least one of a parameter, a configuration, or a solver setting for the entity model, and performs a simulation of the dynamic system model. The device generates a system event during the simulation of the dynamic system model, and modifies at least one of the parameter, the configuration, or the solver setting for the entity model based on the system event.

Dynamic entities for a model of a graphical modeling environment

A time-driven block provided in a block diagram model may be executed in an event domain without user modification. The time-driven block is connected to one or more event-driven blocks using event domain signals. The time-driven block automatically adapts to the execution rules of the event domain modeling and simulation environment. The blocks that are configured to execute in more than one modeling and simulation environments are called polymorphic blocks. The polymorphic blocks are identified during the compilation stage of the block diagram model taking into consideration the port and line styles of the blocks. The execution rules of the polymorphic blocks are also determined during the compilation stage of the block diagram model.

Graphical modeling blocks that execute in more than one domain

A time-driven block provided in a block diagram model may be executed in an event domain without user modification. The time-driven block is connected to one or more event-driven blocks using event domain signals. The time-driven block automatically adapts to the execution rules of the event domain modeling and simulation environment. The blocks that are configured to execute in more than one modeling and simulation environments are called polymorphic blocks. The polymorphic blocks are indentified during the compilation stage of the block diagram model taking into consideration the port and line styles of the blocks. The execution rules of the polymorphic blocks are also determined during the compilation stage of the block diagram model.
