Hello Matlab Forum

I am in the business of creating an Export from Stateflow to a DOORS module.

Taken me a while to get there, but I am happy with the initial creation.

However, I am having trouble updating the DOORS module after some Model changes.

The models concerned are made up of a number of subsystems. I start my script by loading he top level model, then using a

set_param(hModel, 'SimulationCommand', 'Update') ;

command to load the subsystems. I read that the id property found on all States, Transistions and Charts was unique so I hoped to use this for any updates.

Subsequent testing shows that this cannot be relied upon and it depends on which subsystems you load first and maybe a load of other things to.

I unzipped the slx files and looked into the Stateflow.xml, it appears that an Id is persisted into the file for each State/ transition etc and remains constant through iterations, but this is not the same Id exposed through the Stateflow API.

I want a reliable identifier to use to identify states, transitions etc.

Any ideas on how to get this appreciated!!

Thanks for any help

Richard
