Description of Self Test Items C-9
â—¼ Test content
Test whether XCVER data interface between TRB FPGA on the main board and DSP FPGA
works well.
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
XCVER data interface on the connection of TRB FPGA-DSP FPGA goes wrong if the test result is
FAIL.
â—¼ 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 TRB board if the test result is FAIL.
C.1.22 Z0601 PC Module and DSP FPGA Interconnection
Test
â—¼ Top test item
N/A
â—¼ Test content
Test whether PCIe interface communication between PC module and DSP FPGA works well.
â—¼ 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.
â—¼ 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.1.23 Z0602 DSP FPGA DDRIII Test
â—¼ Top test item
PC module and DSP FPGA interconnection test
â—¼ 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
buffer DDR (transmitting scan control frame), IQ buffer DDR (transmitting IQ data) and Gather
buffer DDR (collecting data).
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The connection error between FPGA and plug-in DDR occurs if the test result is FAIL.
