Version 5.1.2

Released: 29 Apr 2004
 

Stateflow 5.1.2 resolves many customer-reported issues.

For additional information about Stateflow 5.1.2, see the Release Notes.

Version 5.1.1

Released: 22 Sep 2003
 

New features

• Bind is a new State Action semantic that allows you to bind data and events to a state. This improves the user’s control over creating and modifying data and issuing events. The main benefit of this semantic is that, when a function-call event is bound to a state, the Function-Call subsystem that is called is also bound to that state, allowing Simulink to be executed within Stateflow
• Object descriptions that you enter in the property dialogs for charts, states, functions, and transitions, are now included as comments in Stateflow generated code for Real-Time Workshop targets.

Performance improvements

• Increased speed in the Stateflow build process for both simulation, and Real-Time Workshop targets.
• Increased speed and reduced memory usage when loading large models with library links that contain Stateflow charts.

Known problems and corrections

Version 5.1.1 corrects the following known problems:

• Errors and model corruptions no longer occur when a library link for a subsystem containing linked Stateflow charts is disabled and then later re-enabled.
• Copying and pasting a Stateflow chart within a library model no longer results in self-referential (circular) links causing model corruptions. Copying a library chart and pasting it into the same library model now creates just a copy of the original chart rather than creating an intra-library link.
• Disabling a library link chart while editing the source chart no longer causes a segmentation violation during simulation.
• Large Stateflow models no longer crash during simulation when using the lcc C compiler on Microsoft Windows-based systems. lcc version 2.4.1, MathWorks patch 1.29 corrects a bug encountered when compiling very large C files. Please refer to Release Notes for more details.
• For models containing multiple instances of a library linked chart that has custom code for a Real-Time Workshop target, the custom code is no longer included multiple times in the generated code
• During Real-Time Workshop code generation, initializing Stateflow data from workspace variables no longer causes errors for logical data types.
