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 DSP FPGA and TRB 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 TRB 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 TRB 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 TRB board if the test result is FAIL.
C.1.18 Z0502 TRB AFE SPI Interface Test
◼ Top test item
DSP FPGA and TRB FPGA communication self test (control interface)
◼ Test content
Test whether the control interface communication between TRB FPGA and AFE’s SPI works well
via reading the register.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
SPI between TRB FPGA and AFE has communication error if the test result is FAIL.
