This document describes how to use On-line BISTs on MPC5777C.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

STCU2 On-line BIST (MBIST+ LBIST) execution time on NXP Evaluation board ( X-MPC5777C-561DS) is 25.8ms.

This measured time is valid for:

System clock PLL = 200MHz

STCU module clock = System clock / 4

MBIST = 50MHz

LBIST = 25MHz

Result after testing MBIST+LBIST = 0 faults latched in ERR_STAT register and all LBISTs was successfully executed.

 

 

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

STCU2 On-line LBIST only execution time on NXP Evaluation board ( X-MPC5777C-561DS) is 37.4ms.

 

This measured time is valid for:

System clock PLL = 200MHz

STCU module clock = System clock / 4

LBIST = 25MHz

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

LBIST on 50MHz

I do not recommend to run LBIST at 50MHz as it was failing in my setup.
