APIS IQ-Software Version 7.0 – 0050 is now available to download. There are many new features and bug fixes that come with this service pack, but here are the highlights:
New Editor: AIAG/VDA Form (MSR) (V7-3638)
The FMEA-MSR Formsheet is now available. This form can be used to analyze the causes that may occur in the category “customer operation” regarding their effects on the system, taking into account safety mechanisms and operating conditions. Safety mechanisms contained in the failure net are displayed in the FMEA-MSR Form. Furthermore, safety mechanisms can be derived from actions that were entered in Section 6 of the MSR form. These safety mechanisms are displayed in the MSR form and integrated into the failure network. Similar to the FMEA Formsheet, various scenarios can also be displayed and evaluated in Section 6 of the MSR Formsheet.
In order to further understand this new feature of the IQ-Software, we have created some articles on the MSR form-columns Current Diagnostic Monitoring, Current System Response, Diagnostic Monitoring Action & System Response. With each of these articles, you can download an .fme file that has taken part of the official AIAG/VDA 2019 Window Lift System example.
Functional Safety: New objects for defining safety goals (V7-128)
Adaptations of “Functional Safety” functionality according to “ISO 26262 Second edition 2018-12”: New objects were introduced for the definition of Safety Goals. Safety Goals can be defined for Structure Elements. The ASIL classification and the assignment of target values can be defined for a Safety Goal. For the violation of a Safety Goal, single faults and multiple faults can be linked via two predefined anchors in the failure net.
FMEDA Form: New columns added (V7-294)
In the FMEDA Form Layout ISO-26262 two columns “Source FIT” and “Source for % value of failure” have been added.
FMEDA Form: Functional Safety Table integrated (V7-209)
The FMEDA Form for ISO 26262 has been revised: The “Functional Safety Table” (Version 6.5) has been integrated into the new layout. Content of a FMEDA Form is now a Safety Goal (New object in V7.0). Based on a Safety Goal and the information available about the failure net, the FMEDA Form is filled in and the corresponding Functional Safety calculations are performed.
