Hi all,
After postRoute i am having a couple of spots that have lot of short due to congestion of cells placed in a small area. There are plenty of space around so i am putting in a density screen of 10%.
I use setOptMode of -moveInst to True.
I re-run optDesign -postRoute again
The tool doesn't move or spread the cells in the area that i place the density screen so the congestion is still there.
Any idea how to spread these cell out without going back to placement, cts opt .....
Thanks
