Description of Self-diagnosis Test Items C-13
Suggestion when test failed
1. Check if the hardware and related circuits listed below are normal, interfaces are securely
welded, modules are normal.
C.1.22 Z0801 PC Module and DSP Interconnection Test
Test Content
Test the PCIeX4 BUS between PC module and CBSP_UPLOAD FPGA
Analysis when test failed
First check if Windows can recognize the Ultrasound DataUpload Device, the malfunction has
appeared ever. If the device can be recognized, there may be communication malfunction between
DSP board and PC module.
Suggestion when test failed
Replacing DSP board is recommended.
C.1.23 Z0802 DSP DDR Test
Test Content
The super stratum test item:Z0702 PC Module and DSP Interconnection Test.
Test the all space reading &writing function of four types of DDR loading by DSP FPGA, output DSP
buffer DDR(transferring DSP middle processing data),SCAN buffer DDR(transferring scan control
frame) and I/Q buffer DDR(transferring I/Q) test result.
Analysis when test failed
If test is failed, there may be connection malfunction between FPGA on DSP and plugging DDR,
which will cause the data communication test item between receiving board/CW board and DSP
board FAIL. The case appeared ever is that FPGA is destroyed in the installation process and
cause the test FAIL.
