Hi All,
I used to write the skill scripts with the combination of Diva rule files.
Long time back, For higher nodes(above 28nm) I had written one script which will extract the power/gnd net and will find out via missing location(at its overlaps). And as per these locations, my skill script will put the vias there.
When I use this script for lower nodes(14nm/7nm), Its not working fine because lower metals(from M0 to M3) has 2 colours with cutlayers.
The problem I'm facing is I can't able to extract M* with mask1 color & M* with mask2 color separately. If its possible then my scripts goes much easier.
Not only this particular script, whatever I want to deal with colour metals using diva rules, its getting difficult to me.
Please tell me if there is any solution.
Thanks & Regards,
Narendra K
