    Hi


    I think the signal tap cannot capture the signal from mem* conduit since it connected to the memory component.

    Therefore, you may not see the signals are triggering in the signal tap.


    You may refer to the simulation test run to observe these signals behavior.

    I think the memory datasheet may has some description in the power up and initialization of memory section that you can refer to.


    Regards,

    i see!

    so,Can I use some methods to see these signals from the signalnap?
