    Hi, 

    Please refer to the table below for details on how each ECC endpoint can be tested using ECC aggregators - 

    ECC Type Inject Type Accessible Mem Checker Type Single bit injection possible? Test Procedure Double bits injection possible? Test Procedure
    ECC Wrapper
    		 Inject only NO N/A Yes SDL APIs can be used only for error injection. Error detection and correction is a part of the IP itself. Yes SDL APIs can be used only for error injection. Error detection and correction is a part of the IP itself.
    Inject with error capture YES N/A Yes SDL APIs can be used, memory access also a part of the SDL ecc_func_app in sdl/test Yes SDL APIs can be used, memory access also a part of the SDL ecc_func_app in sdl/test
