Abstract: Systems and methods receive a model of a physical system. The model includes a virtual mechanical component that represents a physical mechanical component of the physical system, and a virtual transducer that represents a physical transducer of the physical system. The systems and methods include generating a wiring diagram that includes information for connecting the physical mechanical component or the physical transducer to a data processing device or an embedded system. The model may be executed by the data processing device or the embedded system to interact with the physical mechanical component or the physical transducer as part of Hardware-in-the Loop (HIL), Processor-in-the-Loop (PIL), or other simulation or testing.

Abstract: A computing device may be configured to interact with a requirement object using an object-based requirements framework. The computing device may further provide a design to the object-based requirements framework. The design may comply with design criteria of the object-based requirements framework. The computing device may also determine whether the design complies with the requirement object. The determining may be based on the interacting, and may produce a result.

Abstract: In an illustrative embodiment, an apparatus, computer-readable media, or method may be configured to suggest determine relationships. Interaction with a block diagram model may include receiving a first portion of a block diagram model. The block diagram model may include a plurality of blocks. Each of the plurality of blocks may represent a set of dynamic equations. The interacting may be performed using the computer. Relationships between a plurality of a synthesized input, a synthesized output, a synthesized state, or a synthesized derivative, may be determined. A determination may be performed for the first portion of the block diagram model. The determining may include determining a block Jacobian pattern of relationships between two or more of an input, an output, a state, or a derivative of a first block of the plurality of blocks in the graphical model.

Abstract: A version control unit may maintain separate version numbers for multiple traits of a single model. In particular, a number of model traits may be identified, such as a model behavior trait, a software architecture trait, a simulation trait and a code generation trait. Version information for each trait may be maintained separately for the single model. Groups of elements of the model, such as graphical objects, relationships among the objects, object parameters, model parameters, etc., may be mapped to the model traits. The version control unit may determine what model elements are changed since a prior version, and identify the model traits to which the changed model elements are mapped. Version numbers for these traits may be incremented, while version numbers for the other traits may be left unchanged.

Abstract: A device may receive a state chart generated via a technical computing environment. The state chart may include a state block with a single section of textual code. The single section of textual code may include a time-based portion and an output portion. The device may initiate execution of the state chart, and may process, during the execution of the state chart, the time-based portion with a graphical engine of the technical computing environment to generate a time-based method. The device may process, during the execution of the state chart, the output portion with a textual engine of the technical computing environment to generate an output method. The device may provide the time-based method and the output method in output code, where the time-based method may be separate from the output method in the output code.

Abstract: Systems and methods automatically construct a realization of a model from an available set of alternative co-simulation components, where the realization meets one or more objectives, such as fidelity, execution speed, or memory usage, among others. The systems and methods may construct the realization model by setting up and solving a constrained optimization problem, which may select particular ones of the alternative co-simulation components to meet the objectives. The systems and methods may configure the realization, and execute the realized model through co-simulation. The systems and methods may employ and manage different execution engines and/or different solvers to run the realization of the model.

Abstract: According to some possible implementations, a method may include determining one or more inputs to a model of a system and one or more outputs from the model. The method may include identifying a continuous portion of the model to be discretized. The method may include discretizing the continuous portion of the model, using at least one of a continuous linear representation for the model or a frequency response associated with the continuous linear representation, to generate a discrete linear representation for the continuous portion of the model. The method may include outputting information associated with the discrete linear representation to permit the continuous portion of the model to be implemented on one or more processors.
