matlab脚本对simulink数据字典（sldd）的操作-间歇汇总

手动选择文件：

% select .xx file,xx替换为所需格式，文件路径字符串存于DDFile变量中
[xxfile,~,~] = uigetfile('*.xx','Select xx file');
if xxFile == 0
    return;
end

 

sldd to .m

% open .sldd file 
MyDictObj = Simulink.data.dictionary.open('sldd file path');
% export data dictionary entries to mat or matlab file
DataSectObj = getSection(MyDictObj,'Design Data');
% 导出到'file name.m'文件中
exportToFile(DataSectObj,'file name.m');

 

.m to sldd

% open .sldd file 
MyDictObj = Simulink.data.dictionary.open('[sldd file path]');
% export data dictionary entries to mat or matlab file
DataSectObj = getSection(MyDictObj,'Design Data');

　%导入sldd

ImportedVars = importFromFile(DataSectObj,'[yourfile].m','existingVarsAction','overwrite');
saveChanges(MyDictObj)

 

修改sldd中数据的属性，批量修改某属性

使用到的函数/方法:

• getSection

• getEntry

• find

• getValue

• setValue

 

% open .sldd file 

　MyDictObj = Simulink.data.dictionary.open("[sldd file path]");

% export data dictionary entries to mat or matlab file

　dDataSectObj = getSection(MyDictObj,'Design Data');

signal_objects = find(dDataSectObj,'-value','-class','simulink.Signal');
for i = 1:numel(signal_objects)
    signal_obj = signal_objects(i);
    Obj = getEntry(dDataSectObj,signal_obj.Name);
    % 设置信号属性
    a=Obj.getValue;
    a.CoderInfo.StorageClass="Custom";
    a.CoderInfo.CustomStorageClass = 'Default';
    Obj.setValue(a);
    clear("a");
end

 ---2026更新

对Simulink.data.dictionary.Section类型有以下操作方法，可通过调用函数或直接对section类型操作：

addEntry	Add new entry to data dictionary section
assignin	Assign value to data dictionary entry
deleteEntry	Delete data dictionary entry
evalin	Evaluate MATLAB expression in data dictionary section
exist	Check existence of data dictionary entry
exportToFile	Export data dictionary entries from section to MAT-file or MATLAB file
find	Search in data dictionary section
getEntry	Create Simulink.data.dictionary.Entry object to represent data dictionary entry
importFromFile	Import variables from MAT-file or MATLAB file to data dictionary section

 
   % 写入SLDD：同名自动覆盖
    if ~desData.exist(param_name)
        addEntry(desData, param_name, param_obj);%函数方式
        fprintf('写入字典：%s\n',param_name);
    else
        desData.assignin(param_name,param_obj);%调用方法
        fprintf('更新字典：%s\n',param_name);
    end
