Use software programming, such as car diagnostic functions.
1.1 Use IC spec. to design the source code, and review FMEDA to help EE decide the Safety Mechanism.
1.2 Design analog front end based on SWE.3 detail design and SWE.2 architecture design. Accomplish the requirement and test the SPI timing using oscilloscope.
1.3 Using welding torch to modify the PCBA for changing the HW design and create the IS26262 part6 and ASPICE SWE.6 Fault Injection.
