Solution Overview

Problem

Users face difficulties in maintaining consistency among user-settable parameters across various graphical modeling components, especially in complex models with numerous components, as they need to ensure parameters like data types and operations are consistent between related components, such as modulators and demodulators, which can be time-consuming and error-prone without automated checks.

Innovation Solution

A method and system for automatically checking the consistency of user-settable isolated parameters between related graphical modeling components, using a dependency marker to identify associated components and a parameter consistency checker to verify and propagate parameter values, ensuring that parameters remain consistent across the model, even when components are distributed across multiple environments.

AI summary

In one embodiment, a method for checking consistency of user-settable isolated parameters among a first graphical modeling component and a second graphical modeling component in an executable graphical model is provided. The method includes designating that the first graphical modeling component and the second graphical modeling component are related; checking consistency between a first user-settable isolated parameter of the first graphical modeling component and a corresponding second user-settable isolated parameter of the second graphical modeling component; and displaying an error when the first user-settable isolated parameter and the corresponding second user-settable isolated parameter are not consistent with each other.
