Data objects for model-based design

摘要

A method of defining data objects for use with an executable block diagram modeling and code generation system including providing pre-defined data object classes, each of the pre-defined data classes having default attributes, extending the pre-defined data object classes with subclasses, each of the subclasses having user-defined attributes and generating data objects, which are instances of the pre-defined classes and the subclasses.

1. A non-transitory computer-readable medium storing one or more computer executable instructions, the instructions comprising:
one or more instructions that, when executed by a processor, cause the processor to:
access a model,
the model including a parameter or a signal,
the parameter or the signal operating on data, the data being stored in an external data source that is independent of the model;
generate a data object, at least in part, by loading information from the external data source,the data object:
comprising a custom attribute for use in affecting a behavior of an operation performed by the model with respect to the data, the custom attribute having an assigned value;
propagate the custom attribute to the model to define an aspect of the parameter or an aspect of the signal; and
perform the operation by operating on the data object using a block in the model, the operating:
affecting an interpretation of the data operated on by the model, andbeing based on the assigned value for the custom attribute of the parameter or the signal.
