The Secondary Operand

For operations such as XOR you need two operands - a primary and a secondary. Once you have selected a primary operand use this dialog to select the secondary.

Your input data must include:

  • A GDSII Stream File


  • A structure within this file


  • A layer or layers of polygons

Hint - there is nothing that prevents you from using the same GDSII file and structure for the secondary operand - only the layer or layers would differ.

The GDSII file is selected using a standard Browse... button. Once this file has been loaded and scanned you can select your structure by pressing on the Structure... button. This will pop open a list box showing all of the structures in this GDSII file. Highlight one of them to select it.

Once the GDSII file and structure has been selected, click on the Layers... button in order to see a list of layers containing data. Highlight as many layers as you want to be processed.
