Description of Self Test Items C-7
C.1.16 Z0405 DSP FPGA and TRA Interconnection Test
(Data Interface)
â—¼ Top test item
DSP FPGA and TRA FPGA communication self test (control interface)
â—¼ Test content
Test whether XCVER data interface between TRA 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 TRA 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 TRA board if the test result is FAIL.
C.1.17 Z0501 DSP FPGA and TRB Interconnection Test
(Control Interface)
â—¼ Top test item
PC module and DSP FPGA interconnection test
â—¼ Test content
Test whether the control interface communication between DSP FPGA and XCVER of TRB FPGA
works well via reading the register.
â—¼ 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.
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 change TRB board if the test result is FAIL.
C.1.18 Z0502 TRB AFE SPI Interface Test
â—¼ Top test item
DSP FPGA and TRB FPGA communication self test (control interface)
â—¼ Test content
Test whether the control interface communication between TRB FPGA and AFE’s SPI works well
via reading the register.
â—¼ 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.
