Object - Brick Properties

Parent Previous Next

Selecting Object - Brick Properties opens the Brick Properties dialog box which allows you to modify the brick material and subsection size associated with the selected polygon(s). This command is only enabled if at least one brick polygon is selected in your circuit.

This dialog box is also opened by clicking on the Meshing Properties button in the Technology Layers Editor for a Brick Technology Layer.

NOTE: If multiple objects are selected which have different parameters, the entry ''Mixed'' appears in the pertinent text entry box. Changes made in the Properties dialog box will affect the parameters of all selected polygons. If you are modifying the meshing properties of a Brick Technology Layer, any changes will affect the parameters of all dielectric bricks inheriting their meshing properties from this Brick Technology Layer.

Tech Layer: If you wish to associate a dielectric brick with a Brick Technology Layer, you may do so by selecting the desired Tech Layer from this drop list. If you want this dielectric brick to be independent of any Technology Layers, then select <None> from this drop list. This field does not appear when editing the properties of dielectric brick polygons in a project containing no Brick Technology Layers, or when editing the meshing properties for a Brick Technology Layer.

Properties Control (Local/Inherit): If you wish the selected polygon(s) to use the same material and meshing properties as the Technology Layer selected in the Tech Layer drop list, select Inherit from this drop list. If you wish the dielectric brick to have unique properties, select Local from this drop list. Note that when a Technology Layer is selected in the Tech Layer drop list, the properties control is automatically set to Inherit but may be changed. If the Tech Layer drop list is set to <None>, then this drop list is always set to Local. This drop list only appears if the Tech Layer drop list is present.

If a Technology Layer is selected in the Tech Layer drop list and the properties control is set to Local, then the polygon is located in the metal level to which the Technology Layer is assigned. The polygon is also included in an export to a drawing layer or stream. However, in the Sonnet project, the polygon retains its own unique properties which can differ from the material and meshing properties of the Technology Layer to which it is associated.

Brick: Choose a brick type from this drop list. Changing the brick type changes only the brick material. The brick is still within the same physical layer. This drop list is only enabled if the properties control is set to Local or not present.

A new project initially contains only one brick material, "Air". If you have not set up additional brick material choices in the Brick Type tab of the Materials page of the Circuit Settings dialog box, then the pull-down menu only presents one choice of "air".

Subsectioning Controls: Edit the X Min, X Max, Y Min and Y Max text entry boxes and the Edge Mesh drop list to set the subsectioning for the polygon(s). First time users should leave the values set to the default values (X Min=1, Y Min=1, X Max=100, Y Max=100, and Edge Mesh=On).

 Refer to the Changing the Subsectioning of a Polygon in the Sonnet User's Guide for a detailed explanation of these controls.
