This discussion is regarding to check the "alignment structure" is properly placed in GDS or not.
We are placing "alignment structure" in our layout(GDSII) at two location,those are
*Lower left of the cell and rotation is R0
and other one at
*Upper right of the cell and rotation is R90
These structures will be kept at specific distance from the BBOX of cell,but BBOX will be different for different cells.
What is the best option check these "alignment structure" placement in GDS using calibre DRC/Compare GDS?
