Description of Self Test Items C-7
C.1.16 Z0405 DSP FPGA and TRA Interconnection Test
(Data Interface)
Top test item
DSP FPGA and TRA FPGA communication self test (control interface)
Test content
Test whether XCVER data interface between TRA FPGA on the main board and DSP FPGA works
well.
Analysis to test failure
The drive goes wrong if the test result appears Error.
XCVER data interface on the connection of TRA FPGA-DSP FPGA goes wrong if the test result is
FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace TRA board if the test result is FAIL.
C.1.17 Z0501 PC Module and DSP FPGA Interconnection
Test
Top test item
N/A
Test content
Test whether PCIe interface communication between PC module and DSP FPGA works well.
Analysis to test failure
Check whether Windows device manager recognizes Ultrasound Backbone Device. If the drive is
not installed properly, it cannot be recognized.
The drive goes wrong if the test result appears Error.
PC module and DSP FPGA has communication error if the test result is FAIL.
Suggestion to failure test
It is recommended to restore the device (OS+doppler) if the drive is not recognized.
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace engine board if the test result is FAIL.
C.1.18 Z0502 DSP FPGA DDRIII Test
Top test item
PC module and DSP FPGA interconnection test
Test content
Perform read and write tests for entire space of four types DDRs of DSP FPGA. The program
displays the test results of DSP buffer DDR (transmitting DSP processing result data), SCAN
