Stateflow 6.2 and Stateflow Coder 6.2 Release Notes


New Features

User-Specified Transition Execution Order

Stateflow charts now support a mode where you can explicitly specify the testing/execution order of transitions sourced by states and junctions. This is called the Explicit mode. The Implicit mode retains the old functionality, where the transition execution order is determined based on a set of rules (parent depth, triggered/conditional properties, and geometry around the source). In addition, the transition numbers, according to their execution order, are now displayed on the Stateflow chart editor at all times, both in Implicit and Explicit modes.

Note that the old models created in earlier releases load in Implicit mode, thus yielding identical simulation results. Any new charts created are in Implicit mode by default. To change to Explicit mode, use the Chart Properties dialog box.

Stateflow and Embedded MATLAB Support Simulink Datatype Aliases

Stateflow and Embedded MATLAB data may now be explicitly typed using the same aliased types that Simulink uses. Also, inherited and parameterized data types in Stateflow and Embedded MATLAB support propagation of aliased types. Code generated by Stateflow and Embedded MATLAB does not yet preserve aliased data types.

Major Bug Fixes
