What's new?

Highlights in MES Model Examiner® (MXAM) v.6.3

Focusing on user experience, a number of detailed improvements in user feedback and tool behavior is dedicated to enhance the daily work with MXAM. They provide a stable basis for upcoming exciting features.

MXAM v.6.2

Highlights in MES Model Examiner® (MXAM) v.6.2

Clone group detection
The clone group metric identifies groups of subsystems that are almost identical. Such repetitive implementation, potentially created by copy/paste actions during modeling, increases the overall complexity of a model and thus should be avoided.


Improved MATLAB batch execution
A new configuration option for the MATLAB API allows synchronous execution of batch tasks.

Compatibility with Matlab 2019b and TargetLink 5.0

MXAM v.6.1

Highlights in MES Model Examiner® (MXAM) v.6.1

Architectural metrics view

A new view in the report perspective of the MXAM Functional Safety Solution shows MXRAY metrics, supports sorting, and filtering. Tables and trees can be exported to Excel.

MXAM v.6.0

Highlights in MES Model Examiner® (MXAM) v.6.0

Enhance static model analysis with architectural aspects (BETA)

Static analysis of MATLAB models is complemented by MXRAY model metrics to evaluate adherence to architectural design principles. Useful functionalities of the MXAM analysis framework, such as use of parameters, annotations, ignore lists, and reporting options, are also available.

New MXRAY model metrics guidelines and checks (Functional Safety Solution)

MXRAY checks focus on Restricted Local Complexity, Restricted Number of Hierarchy Levels, Restricted Number of Inports and Outports, Restricted Cyclomatic Complexity, and Use of Effective Interfaces.

Update to the Latest Version

  • If you added MXAM folders permanently to the MATLAB path, please remove all of these folders from the path.
  • If you installed the old version in a folder with a version postfix (e.g. x:\project\matlab\mxam_x_x), you can keep that directory as a backup.
  • If you installed without a version postfix, you could rename the old installation directory to one with a version postfix as a backup.

Update from MXAM 1 to a Current Version of MXAM

A migration kit to migrate customer-specific checksets and checks is available upon request.
Please contact


Manual Installation

  • Installer: Install MXAM by executing the setup file (.exe) and follow the setup instructions.
    • The startup of the installation process might take a while depending on the security settings of the client machine.
    • Installation to a write-protected directory: Right click the setup file and execute as administrator.
  • Zip archive: Unzip the archive into any directory

Automatic Headless Installation

  • Run the MXAM installation once on a machine and save your automatic installation data in the Finish Panel to auto-install.xml.
    With this data, you will be able to run the same installation on another similar machine.
  • Configure the auto-install.xml
  • Run the automatic installation: >>[installer-name].exe [ABSOLUTE-PATH/auto-install.xml]

Quick Start

Starting MXAM

  • For MATLAB platform: Open MATLAB, navigate to the MXAM installation directory, and execute >>mxam
  • For other platforms: Start MXAM using the program shortcut or go to the MXAM installation directory and execute mxam.exe

Starting an Analysis

For MATLAB platform:

  • Open a model in MATLAB
  • Press "Analyze" in MXAM
  • Select the model in the artifact dialog
  • Press "Finish"


  • Press "Analyze" in MXAM
  • Press "Open ASCET 6" in the artifact dialog if it is not yet open
  • Press "Refresh" to fetch models from the database
  • Press "Finish"

For Others:

  • In the Project perspective, press "Add..." in the Artifact Section to add an artifact
  • Select the artifact and press "Finish"
  • Press "Analyze"


  • Go to the "Project Guidelines" perspective to see which guidelines will be checked during the analysis.
  • To see the pool of all available guidelines, go to the "Library Browser" perspective and select the "Guidelines" view.

MXAM Videos

In this video, Model Engineering Solutions (MES) will demonstrate how to set up an MXAM project as an mxmp-file. You will learn how to create and configure an MXAM project and how to save and load a project. Since this video is focused on the first step of the MXAM workflow, basic knowledge of the workflow is needed in order to watch this video.

In this video MES will explain how to understand reports and demonstrate how to work with them in order to make your model guideline compliant. You will need to have basic knowledge about the MXAM workflow to watch this video.

  • In the case that the utility function mes_periprocess filtered out all elements of an array, it may have returned one of its dimensions equal to 0 causing an abort for specific checks. This has been fixed. (#8042)

Guidelines, Checks, and Documents


  • mcheck_misra_slsf_016_a: The check parameter MISRA_SL_SF.misra_slsf_016_a.ignoredBlocks has been introduced, so as to ignore blocks from the analysis. (#8097)
  • mcheck_mes_cgtl_4202, mcheck_ds_0103, mes_sdt_sc001, mes_sdt_sc007_b and mes_sdt_sc007_a: Executing one of these checks with TargetLink 5.0 installed, caused Matlab printing a warning message in the command window. This message will be supressed.


  • mcheck_mes_slsf_9103: The check also ignores the System Requirements block as well as System Requirement Items. (#8099)

Bug fixes

  • mcheck_ds_0100: The check aborted if a block with multiple outports, such as an S-R Flip-Flop, was used as a source block for an analyzed block in a TargetLink environment. This issue has been fixed (#8067).
  • mcheck_mes_slsf_9103: The check aborted if no elements to analyze were found. The issue was fixed. (#8089)
  • mcheck_misra_slsf_027_e: For certain modeling patterns, the check gave incorrect failed findings for signals named outside reusable subsystems. The issue has been fixed (#7918).
  • mcheck_misra_tl_4_4, mcheck_misra_slsf_008_a: The checks gave a failed finding for Math Function blocks where the option ‘SaturateOnIntegerOverflow’ is selected but not modifiable due to the selected ‘Function’ property. These blocks are now being ignored. (#8075)
