Visualization for RLC boundaries and Component Groups Categorized as Circuit Elements

You can visualize RLC elements for layout components in HFSS in the same way as they appear in HFSS 3D Layout Components

You can toggle these RLC visualizations with the Show Layout option. The intent is to display each layout component’s component data in its property window similar to that of 3D components. For example, given a 3D layout design with circuit elements, the visualization of circuit elements in the HFSS 3D Layout modeler window can appear as shown below.

When imported as a Layout Component into HFSS, the layout components would appear as shown below.

The names of the circuit elements are also displayed on top of the visualization. When the circuit elements become too small to display due to zooming out, these names disappear to improve the clarity of the window. This visualization of RLC circuits with their names can be turned on/off by toggling the layout component’s “Show Layout” option.

This property page will display the information about each boundary, excitation, circuit element, and component group of the layout component.

Properties window, Component Data tab.

Parameter Support for Layout Components

The circuit element visualization and component data property page supports parametrization. If the location of a circuit element or a part of the description in the component data is controlled by a parameter, changing this parameter will cause the visualization or the property page to update and reflect the change.

For example, in the above example, the layout component has 2 variables as shown below.

Properties window. Parameters tab.

The variable locationX controls the x-location of one of the pins in circuit element U0: 1-2. The variable resistanceVal controls the electrical resistance in circuit element U0: 1-2. You could change the value of these two variables shown below.

Properties window. Parameters tab.

With this variable change, the component’s circuit element visualization updates to reflect this change.

The Properties page for affected Circuit Elements also updates.
