I am using SoC encounter for layout extraction. After I extracted the layout, I use defOut command to extract the location of different cells. The problem is that it return the left-buttom corner of the cells while I need the coordination of its center. Any suggestion?
 

You know the cell size, so you could calculate the centre coordinate.

Since I want this information for all cells, I should write a parser. The thing is that I thought maybe the tool has some configurations for this purpose.
 

You can do this sort of thing quite easily with a small tcl script: e.g.

Code: 
set instances [ dbget top.insts ] 

foreach inst $instances {
    set box [ dbget $inst.box ]
    set coords [ string trim  $box "{}" ]
    set x0 [ lindex $coords 0 ]
    set y0 [ lindex $coords 1 ]
    set x1 [ lindex $coords 2 ]
    set y1 [ lindex $coords 3 ]
   
    set x_centre [ expr ($x0 + $x1)/2.0 ]
    set y_centre [ expr ($y0 + $y1)/2.0 ]
    puts " instance centre = ( $x_centre, $y_centre ) "
   
}


Maybe this is of some use to you...
