Patent ID: 7031902

Claim:
A method for verifying the design of a disk controller circuit to be incorporated into a targeted hard disk drive system, wherein the targeted hard disk drive system comprises a read/write channel and a head actuator, the method comprising the steps of: emulating reading and writing of data in the read/write channel based upon a model of the read/write channel; emulating a behavior of the head actuator during track seek and track following operations based upon an electromechanical model of the head actuator; providing a disk controller design base for defining integrated circuit elements comprising the disk controller circuit; providing a controller environment to support execution and debug of firmware for operating the disk controller circuit; performing a plurality of disk functions according to a script, wherein performance of at least one of the plurality of disk functions comprises the execution of the firmware, and wherein the plurality of disk functions comprise interaction of the read/write channel model, the electromechanical model, the disk controller design base and the controller environment.
