The present application discloses a
host model for front-end
verification of a hard
disk controller, and relates to the field of storage technology. In the
host model of the present application, on the one hand, by constructing a submission model, a completion model, and a
management model, and the submission model includes a submission
queue, the completion model includes a completion
queue, and the
management model includes a pending command array, therefore, based on the submission
queue, the completion queue, and the pending command array, the communication between the host and the hard
disk controller can be simulated to achieve front-end
verification of the hard
disk controller. On the other hand, the submission model, the completion model, and the
management model provide methods that can be called, so that the front-end
verification personnel can complete the front-end verification of the hard disk controller by calling these methods without directly operating the storage space of the host, thereby solving the problem that the front-end verification of the hard disk controller in some technologies is difficult to implement.
