AWR2944: SDL Test Execution Time

qingchao.meng

Part Number: AWR2944

Hi,

I try to calculate the test exectuion time of ECC, So I added test code to log the execution time using function "ClockP_getTimeUsec", Debug_log was commented out the debug_log at the same time.

Then the exeution time of BTCM ECC is around 2 seconds .

But I cheked the execution time of ECC test in doc"AWR294x_Safety_Manual_Functional_V0p601.pdf", it is less than 10ms. why there is so huge gap.

For my understanding this DEF10 software test of Memory ECC is to inject error 1 bit and 2bits and check the reaction , as ECC example does.

Thanks.

Hi,

There are 3 sub system in the device and two arm cores inside the device. One is inside the MSS and the other is inside the BSS. The snippet you provided is for the BSS while SDL example is for MSS. So, there is a mismatch in your reference.

Also, the HW error time refers to the interval when the IP detects the error and then reports it back to the respective sub system. This time cannot be measured easily via timers on silicon. Also this time does not account for Software overheads/delays.

Thanks,

Pradipta.
