Hi Jan,
As shown in the figure attached, the top event of FTA is derived from SG and the FSR is derived from the event of FTA.
So, could the traceability relationship between FSR and SG be created automatically?

Hi Qianqian,
the connection between a SG and a SR is usually much more complex compared to a simple trace: On top of the hierarchy you have a SG and below the top-level FSR's which are connected to the SG with a contributes-Relation. These FSR's may again be split using a substructure-relation into more refined FSR's and also further FSR's can be connected to them using contributes relations. In the next step you would the go to the Technical/HW/SW Safety concepts and again the requirements in these modules are connected to the higher levels using contributes or sub-requirements relations. And finally you have of course also the decomposition of a requirements with an higher ASIL into two requirements with a a lower ASIL.
For that reason the connection between a SG and a FSR derived from the FTA for that SG can not be automatically selected/created by the tool but must be done manually - taking into account company specific rules to organize requirements and also the meaning/content of the requirement and the SG itself.
BTW, in your example I would already assume that the requirement is not a FSR but rather a HW Safety Requirement as it is adressing a failure of a HW Part.
Best regards,
Eckhardt
