Refinement is a notion of equivalence that can be used to check that an ooo processor correctly implements all behaviors of its instruction set architecture (ISA). https://olivebookmarks.com/story19598852/the-development-of-knowledge-enrichment-books-concerning-ice-and-snow-physical-studies-for-high-school-students
