Thread Subject: cvs keyword substitution and external mode

Hello,

is there a way to use cvs keyword substitution in a simulink model without disabling external mode?
I have models running in hardware-in-the-loop tests and frequently use the external mode to look up internal signals. On top level I use a text field for some general model information, and as we use cvs for configuration management I placed a keyword for substitution into that text box. Whenever I check a model in to cvs this will cause an update on the text field. When I want to connect to the realtime model after that I am denied access, because the model has "changed" and some checksum comparisons fail.
How can I avoid this? Is there some region in the model file excluded from the checksum computation or can I influence the external mode to just check something like the models automatic version counter?
TIA,

     Robert

Hi Robert,

A change like that should not alter the checksum. You can use

[checksum, additionalInfo] = Simulink.BlockDiagram.getChecksum(model)

to get more information on the checksums for your model. Can you try this before and after the model has been checked into CVS?
