DRC calibre error

Discussion created by m.torabi on Mar 25, 2014


I have a DRC error and I can't find it in the rule file. I'm usinf TSMC 90nm.

The error is MD.DN.1.

I found that there is a MD layer, but I don't know what is this layer and I used it to increase the  density but it didn't change..

I need to know what is MD layer.


Thank you
