Automatic verification platform and method for on-chip memory management unit fault-tolerant structure

The invention provides an automatic verification platform and method for an on-chip memory management unit fault-tolerant structure. The automatic verification platform and method can conduct random fault injection verification on the fault-tolerant structure and are high in verification coverage rate. The platform comprises a debugging host and a to-be-tested host connected through a serial port. The debugging host is used for flow control verification, encoding result checking, fault injection, decoding result checking in the verification process, and monitoring and debugging of a processor. The on-chip memory stack fault-tolerant structure is integrated in the to-be-tested host and used for generation of check codes, decoding verification after decoding logic and fault injection and loading of an automatic verification program for the memory stack fault-tolerant structure. The memory stack fault-tolerant structure comprises a memorizer control module, a fault-tolerant module, a selector and a memory stack. The memorizer control module and the fault-tolerant module conduct read-write control over the memory stack through the selector to control the working mode and the failure mode of the on-chip memory stack fault-tolerant structure.
