Specifying Options to Remove Dangling Shapes

If the layout contains dangling shapes, you can specify rules in the Remove dangling shapes section of the Simplify layout for EM simulation form to remove those before sending the model to the simulator.

To add a new rule to remove dangling shapes based on their size from one or more layer-purpose pairs in the layout:

1. Select a layer-purpose pair from the Lpp drop-down list.
2. In the Min Layer Size field, specify the minimum size of shapes you want to retain on the layer. The tool removes any shape smaller than the specified size.
   For example, if there are floating metal1 shapes smaller than 10x10 microns, you can create a rule for the metal1 drawing layer-purpose pair to remove all shapes less than 10 microns, as pointed by the red arrows in the following example of a pre-processed layout.
   
   
3. Click Add to create and add the rule to the list in this section.
