Abstract:
A diagnosis test apparatus for a small computer system interface (SCSI) controller, comprising:a host computer for inputting/outputting SCSI control data and SCSI test data; anda SCSI controller for receiving and temporarily storing the SCSI control data and SCSI test data from the host computer and for outputting the stored test data to the host computer, for thus testing the SCSI controller;wherein said SCSI controller includes:a SCSI signal controller for receiving and temporally storing the SCSI control data from the host computer in accordance with a clock signal and a test mode signal;a first SCSI input/output buffer, connected between said SCSI signal controller and a SCSI bus, for buffering the SCSI control data from the SCSI signal controller and for outputting the buffered SCSI control data back to the host computer through the SCSI signal controller.an SCSI test data controller for receiving and temporally storing the SCSI test data from the host computer and for outputting the stored SCSI test data; anda second SCSI input/output buffer, connected between said SCSI test data controller and a SCSI bus, for buffering the SCSI test data from the SCSI test data controller and for outputting the buffered SCSI test data to the host computer through the SCSI test data controller.
