    Hi Mattan,

    I would traverse all the constant directories in the RC hierarchy and use something like

    filter flop true [fanout -endpoint <0|1>]

    This should give you all the flops with a hard connection to constant 0 or 1
    Also, your log should have reported those as they are optimized if you have the optimization enabled
    which I highly recommend. I one of the designs we ran, we found 1000s of flops that were not needed
    and RC optimized for us
