Properties, instrumentation and automatic scaling for signals in a modeling environment

摘要

A method and system are provided for deriving a property value of a data type in a graphical modeling environment. A graphical model in the graphical modeling environment includes at least one signal having a data type having a precision property, a minimum data value property, or a maximum data value property. These properties may be defined by a user of the graphical modeling environment. The graphical modeling environment may also include instrumentation and diagnostics for signals. Heuristics and algorithms may be provided for auto scaling and selection of data types for signals.

1. A method comprising:
receiving, by a computing device and from a user, information defining at least one of a first precision requirement or a first precision limitation of a first signal type of a first signal of a model,
the first precision requirement identifying a level of accuracy required for values of the first signal,the first precision limitation identifying a limitation regarding a rate of change for the values of the first signal; receiving, by the computing device and from the user, information defining at least one of a second precision requirement or a second precision limitation of a second signal type of a second signal of the model,
the second precision requirement identifying a level of accuracy required for values of the second signal,the second precision limitation identifying a limitation regarding a rate of change for the values of the second signal; receiving, by the computing device and from the user, information indicating that the at least one of the first precision requirement or the first precision limitation is related to the at least one of the second precision requirement or the second precision limitation; detecting, by the computing device, a change in the at least one of the first precision requirement or the first precision limitation; determining, by the computing device, whether the change has been propagated to the at least one of the second precision requirement or the second precision limitation; and notifying, by the computing device, the user that the at least one of the second precision requirement or the second precision limitation is to be changed when the change has not been propagated to the at least one of the second precision requirement or the second precision limitation.
