TMS570LS3137: Some problems of CPU SelfTest

Part Number: TMS570LS3137

hi,In the self-test of the CPU, the following items need to be diagnosed. I am not sure about calling the SL_SelfTest_STC (STC_RUN) diagnostic library interface, whether the following diagnostics are included, if not, which interfaces of the diagnostic library should be called for these diagnostics :

(1) Diagnose the instruction set of the CPU, such as MOV, ADD and other instructions. Does TI's safety diagnosis library provide an interface for the diagnosis instruction set? How should this part be diagnosed?

(2) To diagnose the core registers (R0-R15) of the CPU, which interface should be called?

(3) The diagnosis of CPU special function register, flag register and CPU stack? thanks.

  • Hi Xiaohong,

    (1) Diagnose the instruction set of the CPU, such as MOV, ADD and other instructions. Does TI's safety diagnosis library provide an interface for the diagnosis instruction set? How should this part be diagnosed?

    The CPU selftest is to test the digital logic in CPU. It doesn't test the instructions like MOV or ADD.

    (2) To diagnose the core registers (R0-R15) of the CPU, which interface should be called?
    (3) The diagnosis of CPU special function register, flag register and CPU stack? thanks.

    The LBIST test all the digital logic inside the CPU including the logic for MCU registers (R0, R1,....)
