Scheck - SAF SRAM ECC

[Harish_R]

Hi team,

I was working on Scheck SRAM test. Test target side i found there are 2 SRAM_ECC like 

SRAM_0_ECC and SRAM_0_ECC_LITE (LITE version provides faster execution time at cost of lower diagnostic coverage (number of test vectors is significantly reduced). i couldnt understand much about this info. so ECC test is like checking memory as per ECC logic (on Single bit error/double bit error) so less diagnostic coverage actually means??

if someone could drop some more information it would be helpful.

BR,

Hello, @Harish_R 

Thanks fo your post and sorry for late response.

From my understanding, the less diagnostic coverage here may mean that some errors may go unnoticed, and/or some of the noticed fault may not be corrected/handled, which is caused by the number of test vectors is significantly reduced.
