SUMMARY:Achieving High-Integrity Safety for 360-degree Automotive Display 
 SoC's RETIME-IP: A Static Analysis Approach to ASIL-D Compliance
DESCRIPTION:Jerry (Chaojie) Chen and Niko (Bicheng) Guo (Omnivision Techno
 logies (Shanghai) Co. Ltd) and Sesha Sai Kumar C V and Jamil R Mazzawi (Op
 tima Design Automation Ltd)\n\nThe RETIME-IP is a critical component in OM
 NIVISION's image sensor SoC, used in automotive, 360-degree surround-view 
 systems. This IP is responsible for receiving raw data from upstream image
  sources, processing it, and storing it into SRAM for consumption by downs
 tream modules. Given that this SoC is classified as ISO-26262 ASIL-D, the 
 RETIME-IP must also adhere to ASIL-D requirements, in accordance with the 
 ASIL decomposition guidelines set forth in ISO 26262-10:2018, Clause 11. W
 hile the RETIME-IP was initially designed with several safety-mechanisms (
 SMs) to meet the necessary fault coverage, subsequent fault injection anal
 ysis identified the need for additional SMs to reach the ASIL-D targets. \
 nThis paper outlines a novel methodology using a Certified tool as per ISO
 26262-8:11. Using Static Analysis fault classification to find the safety 
 gaps and thereby add SMs only in the areas required without the increase i
 n the hardware. An intuitive way of fault classification to ISO26262 class
 ification is employed.  Also to reduce the faults that need to be simulate
 d, Constant-Analysis, is employed to mark blocked faults as safe. The resu
 lt was not only achieving the ASIL-D SPFM target of 99% but also achieving
  it in much less iterations, thereby saving project time compared to simil
 ar SoC projects.\n\nTopics: AI, Chiplet, Design, EDA, Quantum, Security, S
