7-5-4. DSP_SDRAM
[Contents]
Inspect the connections of SDRAM interface between
DSP#1-5(IC101, IC201, IC301, IC401, IC501) and each
SDRAM.
[Procedure]
<GUI>
Automatic judgment
<Display of inspection log>
In the case of PASS, “PASS: DSP_SDRAM”.
In the case of FAIL, the contents of failure are returned like
“FAIL: DSP_SDRAM IC102 IC202 IC302”.
