Hi,

we wanted to measure tLBIST time has given in the safey manual as below.

Code Implementation :

Issue : 

I am able to get the start time but the EndTime always shows this value 0x80001000.

Is there any way to measure the LBIST execution time ?

Note : I am storing the value in XRAM

Hi kumaresh

As I know, when LBIST starts, the MCU state is lost. 

and when LBIST ends, the MCU should be an internal reset.

so I think measuring LBIST execution time is not possible using SW.

so How about measuring LBIST execution time using HW?

but if SW measuring is possible, please let me know.

thanks
