Hello team,

I am trying to use IN0 as GPI Reset.

Where should I connect this GPI Reset pin? I have no where to connect.

Best Regards,

    Hi Kei,

    You do not need to connect the pin anywhere if you are using it as GPI Reset.

    Hello Ian-san,

    I have created a project to see if GPI Reset works.

    I have set the GPI Reset signal to be HIGH after 2ms, however, the output of DFF is not LOW (initial state) after 2ms.
    In my understanding, if the GPI Reset is HIGH, then the all the system would be at initial state.

    I have attached the project file, so could you please check, and see whats wrong?

    Hi Kei,

    This feature is not implemented in ICS simulation because using it causes the entire device to reset and reload the configuration. As such, its less of a reset for the configuration, and more of a device reset. If you are trying to reset the flip flop, you can add a reset input to the flip flop and connect that to the input pin.

    Best,

    Ian
