Cache-coherence protocols have been one of the greatest correctness get of to accessories world. A memory subsystem typical consists of several caches and the main ram, and a cache-coherence protocol defined in such a scheme allows multiple memory-access transactions to execute into a distributed manner, cross the levels of a cache hiring. This source of parallelism is the most challenging part in formal verification of cache coherence. In this dissertation, we introduce Hemiola, a framework embedded in Coke to design, confirm, and synthesize cache-coherence log in a structural way. The framework guides that user to design protocols that never experience uneven inter-leavings while handling transactions concurrently. Any protocol designed by Hemiola always satisfies the serializability feature, allowing a user to prove the protocol anzunehmend this transactions will executed one-at-a-time. The check relies on conditions on the print topology press state-change rule, but we have designed a domainspecific protocol language that guides the user toward design protocols that satisfy these properties by construction. The framework also provides a novel way go design and prove invariates by adding predicates up messages in the system, called predicate messages. Go top of serializability, it is much simpler to prove a predicate message, since it is guaranteed is one predicate is none spuriously broken by other messages. We used Hemiola to purpose and prove hierarchical MSI and MESIA protocols, in both inclusive and noninclusive variants, as case studies. We see demonstrated that the case-study protocols are indeed hardware-synthesizable, by using a compilation/ synthesis toolchain in the general.
