MXAM v.6.3

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.

► All Release Notes

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.



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]


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.

  • The following guidelines are now checkable:
      • jc_0011, jc_0131, jc_0141, jc_0201, jc_0211, jc_0222, jc_0231, jc_0232, jc_0241, jc_0242, jc_0243, jc_0244, jc_0245, jc_0246, jc_0247, jc_0481, jc_0795, jc_0796
      • na_0002, na_0009, na_0016, na_0017, na_0019, na_0021, na_0022, na_0025, na_0034, na_0036, na_0039
      • db_0081, db_0110, db_0123, db_0144
  • The above guidelines are now included in the following documents:
      • MXAM Starter Set
      • MXAM Starter Set - Extended Version (available in Functional Safety Solution)
      • MES Modeling Guidelines for Implementation with Embedded Coder
      • MES Functional Safety Modeling Guidelines for Implementation with Embedded Coder (available in Functional Safety Solution)


  • Combined state actions in a state label in Stateflow could not be read properly causing a false failed finding in specific checks. This has been fixed. (#7890)
  • Improved robustness of evaluating TargetLink data dictionary variables for cases where ‘ddv()’ was used. (#8248)
  • mcheck_jm_0010_a: The check parameters MAAB.jm_0010_a.AllowedPrefixOrSuffixForInport and MAAB.jm_0010_a.AllowedPrefixOrSuffixForOutport have been introduced, so as to insert those prefixes and suffixes that are allowed to be used in the port names throughout the model. (#8313)
  • mcheck_sdt_sa003: The check parameter SDT.sa003.AllowedClassForConstant has been introduced. Now the control signal of the Switch block can originate from a TargetLink Constant block with the variable class defined in the check parameter. (#8486)

Bug fixes

  • mcheck_misra_slsf_006_b: The TargetLink documentation block ‘Autodoc Customization’ is excluded from the check analysis. (#8299)
  • mcheck_misra_slsf_022_a: The check gave a failed finding for missing Model Info blocks on the top-level of Variant Subsystems. This has been fixed. (#8312)
  • mcheck_misra_slsf_026_b:
      • If a block had a named constant but its block name was different from the named constant, then the check gave no failed finding if there was another block in the same subsystem whose name was the same as this named constant. This has been fixed. (#8298)
      • The check can now handle wildcard entries in check parameters.
      • The parameter ‘Sample time’ is excluded from the check analysis for all blocks.
  • mcheck_sdt_sc006: The check aborted when analyzing Inport blocks that have no signal connected, as e.g. Inport blocks on the top-level of Variant Subsystems. This has been fixed. (#8314)
  • mcheck_na_0008: The attempt to automatically repair signal lines related to library blocks triggered a check abort. The check now returns an unrepaired finding. (#8318)
  • mcheck_ds_0067: The check aborted while evaluating the compiled size of specific Stateflow data items. Now, MXAM gives a warning finding instead. (#8248)
  • mcheck_misra_slsf_025_a_1: Due to the incorrect setting of the find_system parameter ‘LookUnderMasks’=’graphical’ the check did not analyze each model level. This has been fixed. (#8374)
  • mcheck_db_0140: The check gave an incorrect failed finding for the ‘Table’ property of TL_Lookup2D blocks. This has been fixed. (#8273)
  • mcheck_misra_slsf_006_c: Bitwise Operator blocks got a failed finding for the ‘BitMask’ property even if the property ‘UseBitMask’ was set to ‘off’. This has been fixed. (#8336)
  • mcheck_misra_slsf_027_e: The check gave a false positive finding for signals inside library blocks if the corresponding output signal of the library block was named. This has been fixed. (#8398)
