    $L AND <layer1> <layer2> <output_layer>

      Hi,

       

      I am doing '$L AND <layer1> <layer2> <output_layer>' on a gds, where layer1 is on level 0, and lay2 is in subcells.

       

      Once I execute this command nothing come out.  Anyone has any idea?

       

      Does 'AND' operation only work when both layers are in the same cell?

       

      Thanks,

      Anderson

          Hi Anderson,


          $L AND command does the operation on a cell-by-cell basis. There are two ways to get the AND operation throughtout all layers.

           

          1.  You can use GUI Layer -> Boolean... and choose "All levels" in the pop-up dialog.

          2.  You can use layout copy command to flatten the entire layout to a new layout handle and do AND on the derived layout.
