Check Name

AUTOSAR CRC Observation check

​
Description

This check monitors the CRC of a PDU or a single signal group of a PDU. The check condition is violated if the calculated CRC does not match the value of the CRC signal contained in the PDU or signal group. The check can be set up for a single PDU or a single signal group within a PDU. The functions/constructors without the parameter signalGroup monitor all specified CRCs within the given PDU. The numeric functions/constructors with the parameter aHeaderId cannot be used for FlexRay. Note: Dependent on the used parameter type, the appropriate bus context in a multibus environment has only to be set before the function is called if the corresponding database object will be ambiguous. Further information on site MultiBus Environment.

​
Parameters

  • aPDU: Must exist in the database.
  • aHeaderId: PDU header ID to be observed. The corresponding PDU shall be defined in the database.
  • signalGroup: CRC of signal group to be observed.

​
Return Values

  • 0: Check could not be created and must not be referenced.
  • > 0: Check was created successfully and may be referenced using the returned (handle-) value.

​
Possible Errors

  • Specified PDU object does not exist in the database.
  • Given PDU or signal group does not contain a CRC signal.

​
Example

// checks the payload gaps of the message
checkId = ChkStart_CRCObservationAsrPDU (PDUToObserve, "signalGroup1");
TestAddCondition(checkId);
// sequence of different actions and waiting conditions
TestWaitForTimeout(1000);
TestRemoveCondition(checkId);
