  • To distinguish the layers, the full name of the layer needs to be turned on in the LSW window

As the layers are displayed in LSW window in icfb version 5.0; For purpose layer displayed in version 5.1, pls refer table C3

Explanation of symbols:

  • - = Layer illegal for the device

  • + = Layer allowed to overlap

  • D = DRAWN indicates that a layer is drawn by Design.

  • C = CREATED indicates that the layer is only created by CAD.
