hi，
(1) if i want to diag sram use PBIST method Periodic，what do i need to pay attention to ?
(2) Because the PBIST test is a destructive test，so I need to Save user data，there is 64K*4 SRAM,four Block SRAM,Our data may occupy 1 64K SRAM is enough, the remaining SRAM is in the idle state, in the cycle diagnosis, can the data of SRAM 1 be copied to SRAM2, save the data, and then diagnose SRAM1, after completing the diagnosis of SRAM1, Copy the data to SRAM1 and restore the data. Is this design okay? I still have a question about the rate at which SRAM copies data. Do you have such test data?
