Hi,
When working with Simulink models that contain numerous internal and external buses, you can customize the generation of bus object reports to focus only on the top-level buses. Here’s how you can specify which buses to include in the report:
Steps to Generate a Report for Specific Buses
1. Identify Top-Level Buses:
- First, determine which buses in your model are considered "external" or "top-level". This typically refers to buses that are inputs or outputs of the top-level model, as opposed to those used internally within referenced models.
2. Use the `Simulink.Bus.createObject` Function:
- This function can be used to generate bus objects for a specific model or subsystem. You can specify the scope of bus object creation to limit it to the top level.
3. Filter Buses by Scope:
- Use the `Simulink.Bus.createObject` function with additional arguments to specify the scope. For example, you can target only the top-level model without descending into referenced models.
% Example for creating bus objects only at the top level of a model
modelName = 'your_top_level_model';
% Load the model if it's not already loaded
load_system(modelName);
% Create bus objects only for the top level
busInfo = Simulink.Bus.createObject(modelName);
% busInfo will contain details about the buses created
% You can filter or process busInfo to focus on top-level buses
4. Generate Report for Specific Buses:
- Once you have identified the top-level buses, you can generate a report selectively. You may need to write a custom script to filter `busInfo` to include only the top-level buses.
5. Custom Script for Reporting:
- Write a custom MATLAB script to filter the `busInfo` structure and generate a report only for those buses. You can loop through `busInfo` and check the hierarchy or parent system of each bus to determine if it is a top-level bus.
6. Automate and Refine:
- If you frequently need to generate reports for specific buses, consider automating this process with a MATLAB script or function that encapsulates these steps.
Example Script to Filter and Report
Here's a simple example to illustrate filtering and reporting:
% Load the top-level model
modelName = 'your_top_level_model';
load_system(modelName);
% Create bus objects for the top level
busInfo = Simulink.Bus.createObject(modelName);
% Filter the busInfo for top-level buses
topLevelBuses = {}; % Initialize a cell array for top-level buses
for i = 1:length(busInfo.busNames)
busName = busInfo.busNames{i};
% Check if the bus is at the top level (customize this condition as needed)
if isTopLevelBus(busName, modelName)
topLevelBuses{end+1} = busName; %#ok<AGROW>
end
end
% Generate a report for the top-level buses
generateBusReport(topLevelBuses);
% Helper function to check if a bus is top-level
function isTop = isTopLevelBus(busName, modelName)
% Logic to determine if busName is a top-level bus in modelName
% This is a placeholder for actual logic based on your model structure
isTop = contains(busName, modelName); % Example condition
end
% Function to generate a report for specified buses
function generateBusReport(busNames)
% Logic to generate a report for the given bus names
% Placeholder for report generation code
fprintf('Generating report for buses: %s\n', strjoin(busNames, ', '));
end
Additional Tips
- Review Model Hierarchy: Understanding your model hierarchy will help in accurately identifying and filtering top-level buses.
- Documentation: Consult the MATLAB documentation for `Simulink.Bus.createObject` and related functions for additional options and parameters that may be useful for your specific use case.
