regarding metal overlap shape

varunkumar

Hi,

 

I want to put the auto via between metals through skill. I am able to calculate the intersection area through layer AND operation .But i am not able to calculate that which metals are available in the area.  Like If I know that M1 or M2  or any combination of metals are there then only I can put the corresponding via. Kindly help me in this.

     You can use dbGetTrueOverlaps to find all the shapes which overlap an area (if it is a point, just give it a list that is pair of the same point). You can specify the hierarchy level to search and it will return a hierarchical list of the database ID's. You can then loop through the results to determine which layers are available for connection.
