Integrated systems testing
A hard disk drive system includes an external interface that receives test configuration data, that transmits test result data, and that transmits and receives application data. The hard disk drive system includes a system on chip (SOC) that includes a controller and a read/write channel that communicates with the controller and that includes an integrated system test (IST) module that communicates with the external interface. A memory module communicates with the SOC and includes memory and an IST module. The hard disk drive system includes a spindle/voice coil motor driver module that includes an IST module. At least one of the IST modules is a master IST module that receives the test configuration data and that configures the IST modules for testing at least one of the controller, the read/write channel, and the memory module.
