The invention discloses an extension Cache Coherence protocol-based multi-level consistency domain simulation verification and test method. An extension Cache Coherence protocol-based multi-level consistency domain CC-NUMA (Cache Coherent Non-Uniform Memory Access) system protocol simulation model is constructed. A protocol table inquiring and state converting executing mechanism in a key node of a system ensures that a Cache Coherence protocol is maintained in a single computing domain and is simultaneous maintained among a plurality of computing domains, and accuracy and stability are ensured by intra-domain and inter-domain transmission; and a credible protocol inlet conversion coverage rate evaluating drive verification method is provided, transactions are processed by loading an optimized transaction generator promoting model, a coverage rate index is obtained after the operation is ended, and the verification efficiency is increased in comparison with a random transaction promoting mechanism. Through constructing one multi-processor multi-consistency domain verification system model and developing relevant simulation verification, the applicability and the effectiveness of the method are further confirmed.
