GUIDELINES USING MATLAB. ®.,. Simulink. ®., and Stateflow. ®. Version MathWorks Automotive Advisory Board. (MAAB). July 27 th. All versions of the Architectural Access Board’s regulations ( CMR) – Present. The MAAB Control Algorithm Modeling Guidelines (MathWorks Automotive Advisory Board)[3] is a well established set of publicly available rules for modeling.

Check return value assignments in Stateflow graphical functions. Maintaining signal flow when using Goto and From blocks ID: Stateflow and Mmaab interface signals and parameters Last Changed V2. The following sources are not allowed: If you do this, the signal lines coming into and out of the subsystem block should be clearly labeled in close proximity to the block.

Similar block types on the model levels ID: Location of Simulink functions.

Select a Web Site Choose a web site to get translated content where available and see local events and offers. Placement of the default transition.

Simulink model appearance ID: Port block name visibility in Simulink models ID: Gkidelines character usage in signal labels. Description Use of Subsystems The use of switch constructs should be limited, typically to 3 levels. However, a human, understandable, informal description must always be provided for daily reference. The Trigger port is also the function-call block.


Model Advisor Checks for MAAB Guidelines – MATLAB & Simulink

Port block in Simulink models. Rationale Readability Last Changed V2. You can add project or vendor fields to this template as long as their meaning does not overlap with existing fields.

In this presentation of the MAAB guidelines, MathWorks includes a Model Advisor check field in guideline descriptions, which contains the title of and a link to the corresponding Model Advisor check, if a check exists. Control flow signals are output from: Port block names in Simulink models the same name as the associated signal, or giving them a shortened or mangled version of the name of the associated signal.

Exception Guidelinnes logical expression may contain more than two primary expressions if both of the following are true: We need your help to maintenance this website.

Labels should be located consistently below horizontal lines and close to the corresponding source or destination block.

Use of unary minus on unsigned integers in Stateflow. All Examples Functions Blocks. No active subsystem ifFUNC not equal to 1 or 2. Triggered, enabled, conditional Subsystems. Note The selected font should be portable for example, the Simulink and Stateflow default font or convertible between platforms for example, Arial or Helvetica 12pt. Port block names in Simulink models.

Use Bus Selector blocks only with a bus signal input; do not guideelines them to extract scalar signals from vector signals. Unconnected signals, block inputs and block outputs The preceding guidelines apply to signals and signal labels.


The Stateflow software should invoke the execution of the subsystem, using a function call. Correct Variable of loop counter must not be used other than loop counter. Appropriate implementation of fundamental logical and numerical operations. Use of local language in Simulink and Stateflow Note It is possible that Simulink cannot open a model that includes local language on different character encoding systems. Flowchart patterns for conditions Equivalent Functionality Flowchart Pattern Two or more conditions, multiline form: Check use of default variants.

Flow chart patterns for If constructs. All Examples Functions Blocks More.

Maab Guidelines

You can change the settings during the development process. Display guideljnes labels on signals ID: If the signal label is visible in the originating block icon display, the connected signal does not need to have the label displayed, unless the signal label is needed elsewhere due to a destination-based rule. Use of hard equality comparisons for floating point numbers in Stateflow. The model must be referenced using the Model block.
