C-8 Description of Self Test Items
C.1.12 MF FPGA Memory Test
Top test item
N/A
Test content
The program will read the relevant register and check whether the memory is normal.
Analysis to test failure
If the test fails, the memory is abnormal.
Suggestion to failure test
It is recommended to replace PC carrier board if the test result appears FAIL.
C.1.13 Front End Voltage Monitor Test
Top test item
MF FPGA and system monitor interconnection test
Test content
Read A12_ACDC, DP3V3, AP2V1, DP5V, AP5V7, N12V, N5V7, AP2V9, STB5V, AP3V8 on
DC-DC board and AP1V4’s voltage value via ADT7462, and decide whether they meet the
requirements.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The voltage value does not meet the requirement if the test result appears 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 DC-DC board if the test result is FAIL.
C.1.14 DSP FPGA and TRA Interconnection Test (Control
Interface)
Top test item
PC module and DSP FPGA interconnection test
Test content
Test whether the control interface communication between DSP FPGA and XCVER of TRA FPGA
works well via reading the register.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The connection error between DSP FPGA and TRA FPGA occurs 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 change TRA board if the test result is FAIL.
