I am designing a digital block which has stripes on the top metal used to route signals over the block. I created them with the addstripes command. The stripes are connected to a floating output pin of the digital block and specified as a gnd net. This is done via the
set rda_Input(ui_gndnet"pin name").
Now my concern is whether the parasitic effect of the floating top metal is considered in timing analsysis or not.
To confirm i extract spefs with and without the stripes (same encounter run), but the capacitances are exactly the same. I can see the capacitance to drop to 0 for the net name(without stripes added). I have enabled coupled capacitances too.
Can someone give any ideas on how to confirm that the capacitance is actually used in timing checks.
Thanks and best regards
