What is safety critical systems?
Any failure could result significant damage or harm to human.
Where this systems can be found?
Medical
Aviation
Industrial Controls
Nuclear
Transportation
To prevent the significant damage or harm to human, what should we do?
Risk analysis to identify hazards and evaluate the risks
Documentation with certain constraints(i.e. response time, power consumption, memory usage)
Testing and validation
Implementing redundancy to enhance reliability(i.e. dual channel pattern - homogeneous or heterogeneous)
Comply with industry-specific standards/regulations to minimize failures
