摘要

The theoretical development path of a safety-critical system is for a SILx (where 1 <= x <=4) => safety standards -> development + independent safety team + ISA -> safety certificate -> OK to operate. This development path, unfortunately, is followed mostly when formally required or imposed by the buyer, line operator, or grant authority, and this formalization is not a reality all around the world. This talk presents the process that is normally applied to certify safety-critical systems, the differences and pitfalls around the world, and briefly discusses the drawbacks and trade-offs of using automatic tools to replace manual development processes.
