C-18 Description of Self-diagnosis Test Items
If prompt “Probe Board and Receiver Board Interconnection Test :FAIL”，there may be malfunction
on SPI control BUS between receiving board and probe board.
Suggestion when test failed
Replacing the probe board first to see if the problem is solved, and then the receiving board.
C.1.35 Z1301 CW Board and DSP Board Interconnection Test
Test Content
The super stratum test item：Z1001 BF1 FPGA and DSP FPGA Interconnection Test
Test the connectivity of control BUS between DSP FPGA and CW FPGA, output CW board ID and
logic version.
Analysis when test failed
If prompt “CW Board and DSP Board Interconnection Test(Control Interface) test FAIL;”，there
may be malfunction on control BUS between DSP board and CW board.
Suggestion when test failed
Check CW board, communication mother board and DSP board.
C.1.36 Z1302 CW and DSP Interconnection Test (Data Interface)
Test Content
The super stratum test item：Z1201 CW Board and DSP Board Interconnection Test
The connectivity test of data BUS between DSP FPGA and CW FPGA. The test data of I/Q is put
into DDR on DSP by CW board, then is judged correct or not.
Analysis when test failed
If prompt “CW and DSP Interconnection Test (Data Interface) test FAIL.”，check if the test item
“Z0702 DSP DDR Test” is PASS，if FAIL，there may be malfunction on reading memory of DSP
board; if PASS, there may be malfunction on data BUS between DSP board and CW board.
Suggestion when test failed
First option is to change CW board, and then the DSP board.
C.1.37 Z1303 CW SPI Test
Test Content
The super stratum test item：Z1201 CW Board and DSP Board Interconnection Test
The connectivity test of SPI BUS between CW FPGA and AFE.
Analysis when test failed
If prompt “CW SPI test FAIL.”， there may be malfunction on SPI BUS between CW FPGA and AFE.
Suggestion when test failed
Replacing the CW board is recommended.
