I know that there are two kinds of metal fill viz, grounded dummy metal fill and floating dummy metal fill.
By using grounded dummy metal fill the de-coupling cap increases on the signals and thus induces a delay factor in near-by signals. I don't understand how floating dummy metal fill will affect the coupling capacitance or induce cross talk. Can someone please help me figure out this? :thinker::-x
