Core filler not getting inserted below vertical power stripe

Smriti Gupta

I am using Innovus Implementation system V15.20 for my design flow, 

My design contains custom made cells for which lib and lef file has been generated manually (using liberate and abstarct tool respectively), 

During the backend flow, when I'm trying to insert core filler in the post routed design. I see that the core filler is not inserted below the vertical 

power stripes which is causing DRC violations in the design. 

Please help me fix this.

The picture of filler cell not inserted in the design is attached and the command used for filler cell insertion is : 

addFiller -cell feedth9 -prefix FILLER -doDRC
addFiller -cell feedth3 -prefix FILLER -doDRC
addFiller -cell feedth -prefix FILLER -doDRC

Thanks in advance.
