Stateflow

R2012b introduces a major update to Stateflow with a new editor, tabular state machine representation, MATLAB as the action language and an integrated debugger.

Introducing the New Stateflow Editor :56
Navigate Stateflow diagrams and Simulink models through tabs.

State Transition Tables 4:53
Model state machines using the tabular interface in Stateflow.

Integrated Debugger 2:56
Step through a simulation and monitor data in a state diagram.

MATLAB as the Action Language 3:54
Build state machines that use MATLAB as the action language, featuring syntax auto-correction.

Stateflow Editor Assistance :50
Move and arrange objects in state diagrams easily with smart guides, transition indicator lines, drag margins, and just-in-time error notification.

New Features at a Glance

• New editor for Stateflow charts and Simulink models with tabbed windows and model browser tree
• Editing assistance through smart guides, drag margins, transition indicator lines, and just-in-time error notifications
• State transition tables that provide tabular interface to model state machines
• MATLAB language for state and transition labels with chart syntax auto-correction
• In-chart debugging with visual breakpoints and datatips

Version 7.8, part of Release 2011b, includes the following enhancements:

• Chart property to control saturation for arithmetic operations
• User interface enhancements for logging states and data that improve consistency with Simulink
• Control of default case generation for switch statements in generated code (requires Embedded Coder software)
• Detection of state inconsistency errors at compile time instead of run time
• Modeling of persistent output data with Mealy charts

Version 7.7, part of Release 2011a, includes the following enhancements:

• Right-click option for setting local breakpoints
• Use of MATLAB expressions to specify data size
• Options to debug a specific chart in a model and to change data values while debugging
• Atomic subcharts that support input events and enable control of generated function names
• Arrays of buses passed as chart inputs and outputs
• Option to maintain highlighting of active states after simulation
• New signal logging format using MATLAB timeseries class, with simplified access to states and local data
