Mark Net in Virtuoso-L

threepwood06

Hi all,
I have troubles using the Mark net tool, maybe you could help out.

In this example for the test I try to highlight a simple net (that does not propagates too much in the layout) called "pwr_i", here in metal 2 (purple).
I do: Connectivity > Mark net, and then press F3, and in the MarkNet Options windows go in Via Layers tab and -for the test- deselect all but (M2) (V2) (M3).


The result is plenty of other unattached signals are highlighted: in this example you can see the "en" signal (horizontal) and even the thick exclude layers (on the left) are highlithed as well...

What do I do wrong ?

Thanks for your help and best regards

    Ho, I understand.

    But our kit at GF does not allow us to use these objects.

    Furthermore the founders usually use Calibre and do not care on how the excludes are made in Cadence environment :-)

    And to finish the layouters usually do not like using objects as they are not handy (so as for Virtuoso-XL)  :-)
