Compilation error using Stateflow

Problem

I have a model with several CPU, and one CPU is using stateflow. The model is running good offline but at separation I have a big Matlab crash :

"-------------------- Starting compilation --------------------

What could be the cause and is there a workaround ?

Answer

This is due to a current limitation of RT-LAB separator with R2008a : so far using Stateflow is not compatible with using several CPUs. The only workaround is (if possible) to include all computation into a single sm_ subsystem.Keywords : Stateflow, assertion, separation

Update

This problem is now fixed starting fromRT-LAB 10.1.2.
