The BIST (Built-In Self Test) module is an IP block present in K3 devices
|
|
that support triggering of BIST tests, both PBIST (Memory BIST) and LBIST
|
|
(Logic BIST) on a core. Both tests are destructive in nature. At boot, BIST
|
|
is executed by hardware for the MCU domain automatically as part of HW POST.
