C-2 Description of Self Test Items
C.1.3 Z0202 MF FPGA and System Monitor
Interconnection Test
◼ Top test item
Communication self test between PC Module and MF FPGA
◼ Test content
Test the Smbus communication between the MF FPGA and ADT7462.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The error between MF FPGA and ADT7462 occurs 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 PC carrier board if the test result appears FAIL.
C.1.4 Z0203 Back End Voltage Monitor Test
◼ Top test item
MF FPGA and system monitor interconnection test
◼ Test content
Read VCC5V, VDD1V8, VDD2V5, VDD1V2, VDDN5V7 and voltage value of button battery via
ADT7462, and decide whether it meets the requirement.
◼ 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 button battery if VDDBAT voltage appears FAIL.
It is recommended to replace the PC carrier board if the other voltages appear FAIL.
C.1.5 Z0204 System Temperature Test
◼ Top test item
MF FPGA and system monitor interconnection test
◼ Test content
Read temperature values of PCT1, PCT2 and PCT3 via ADT7462 drive and read temperature
values of four CPUs via bottom drive. Decide whether they meet the requirements.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The temperature 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.
