AUTOSAR Tab (Scalar Elements)

The AUTOSAR tab is only available for elements in AUTOSAR components. It contains the following elements.

Policy combo box

The combo box is used to set the AUTOSAR <SW-IMPL-POLICY> element of the <DATA-DEF-PROPS>.

The following settings are available.

Several restrictions apply.

• MEASUREMENT-POINT and QUEUED are only available for variables in AUTOSAR SenderReceiver interfaces.

• If MEASUREMENT-POINT is selected, the following applies:

  • The variable must not be read. If the variable is read, an error MMdl285 is issued during code generation.

  • In the properties editor, the Write option in the Calibration Access area must be deactivated.

    If it is activated, a warning WMdl283 is issued and the option is deactivated.

• If QUEUED is selected, the following applies:

  • The variable must be read explicitly. If it is read implicitly, an error MMdl285 is issued.

  • In the properties editor, both options in the Calibration Access area must be deactivated.

    If at least one option is activated, a warning WMdl283 is issued and the options are deactivated.

• CONST and FIXED are only available for elements in AUTOSAR Calibration interfaces.

• If CONST is selected, only the Read options in the Calibration Access area of the properties editor may be activated.

  If Write is activated, an error MMdl283 is issued.

• If FIXED is selected, both options in the Calibration Access area of the properties editor must be deactivated.

  If at least one option is activated, a warning WMdl283 is issued and the options are deactivated.

Invalidation Policy combo box

With AUTOSAR, you can specify if a value may become invalid (e.g., due to a broken sensor).

The following selections are available:

• replace

  A received invalid value is replaced with the init value.

• don't invalidate

  Invalidation is switched off.

• keep

  A received invalid value is kept and dealt with.

• external Replacement

  The actual value is replaced by the value taken from the replaceWith attribute.

If you select a value other than don't invalidate, an invalidation policy entry is written to the interface description <SWC_name>_interfaces.arxml. The following code extract shows examples.
