Goto/From Simulink

[Pedro Valadares]

When I try to build in Real-Time Workshop, Simulinks shows this error:

Error building Real-Time Workshop target for block diagram 'model'. MATLAB error message:
Error using ==> rtwgen
--> Goto/From connections cannot cross nonvirtual subsystem boundaries. The only exception is when a goto is connected to a state output port.
--> Invalid connection starts with 'pathGoto/Goto3'.
--> Invalid connection ends with 'pathFrom/From'.

All my Goto Tags are "GLOBAL" so it is not a problem with the Visibility.
The Goto block is in the Root level.


This error happens when I try to use the From in a subsystem (should be no problem... Visibility is GLOBAL...). However if I use From block in the same level it works (it also works if I put the Goto block inside a subsystem and use the From in the root level).
Do you have any suggestion to solve my problem?

Got it ;)
You can't use the "Enable" block.

I have the same problem. My from block is connected to

the enable port of an enabled subsystem. Why can't I use
this block? And how to do without? Is there any solutions?

Thank you for your help.

You can use StateFlow.
It sure is not the most efficient way but it does solve your
problem.

How do you use the stateflow? I tried looking at the clutch example but I don't get it. I even tried creating a simple example but I can't pass a goto block to a from block that is in an enabled subsystem. I tried the integrator block while enabling the state port but I just don't know how to use it properly.

Can anyone give me an example?

I had the same problem. The reason is, that the system was declared as an atomic unit. To solve this problem, you have to open Subsystem parameters dialog box (context menu) and to uncheck the Checkbox for "Treat as atomic unit"
