How to check the text syntax of a Simulink model

I want to check if the mdl file of a Simulink model is syntactically correct or not. I don't want to load the model because I am only interested in the syntax errors, not the semantic issues (i.e. unconnected lines, etc.) Consider the example:

Model {
Name toy
System {
Name toy
Block {
BlockType DiscreteTransferFcn
Name "cfblk1"
}
Block {
BlockType Display
Name "cfblk2"
}
Line {
SrcBlock "cfblk1"
SrcPort 1
DstBlock "xyz"
DstPort 1
}

}
}

Here, the model is syntactically correct, but semantically the Line is not correct. Because there is no existing Block titled xyz. If I load the model then it will raise warnings:

Warning: sample.mdl, line 18: Attempt to set DstPort with invalid Destination
> In load_system (line 21)

Is there any way to validate the syntax of mdl files without loading them into memory first?

Hi @Mohammad Rifat Arefin,

I understand that you are looking for a Simulink utility to check a Simulink model for syntax errors without loading it into memory. However, Simulink does not provide such a utility.

When simulating a model, it is necessary to open the system and load it into memory. You can use the open_system("your_model.mdl") command to open your system and load the model into memory. You can verify if the model is loaded using the slreportgen.utils.isModelLoaded('your_model.mdl') command.

Unfortunately, there is no built-in Simulink feature that allows you to check the syntax of a model without loading it into memory. However, you can create a custom external script to check for syntax errors. This script can implement your own logic to identify and report any syntax errors in the model. This way, you can achieve your requirements.

I hope this clarifies the situation.
