I am usi ng Virtuoso ADV 12.1 version.
I have some problem with Double Patterning.
I am assigning colors the nets i have drawn. but how to assign colors to the internal pcell metals.
Let us say i have a net colored to mask2, it is connecting to the drain terminal of the PCell. but inernally the PCell is colored with the mask1. So how to change this internal cell mask.
Here mask2 means I am drawing the layer of mask2.(let us say M1 Exposure1)
is there any thing to change the internal terminal coloring.

It will depend on the capabilities in the pcell. Some pcells are now being created with coloring which is controlled by the parameters on the pcell. Others are inheriting their color based on their connections. You have to go to the pcell/PDK supplier to determine how the coloring is assigned in the cell.
