If you wish to translate your ADS design layout into a Sonnet project but not execute a simulation, you may use the Sonnet ⇒ Tools ⇒ Translate Only command, available in the main menu of the layout window. When you select the command, the Save As Sonnet dialog box appears whose purpose is to display the project to which the translation will be written. You may select any location and project name. When you click on the OK button the ADS design is translated and written to the specified Sonnet project.
If you edit the project in Sonnet be aware that there are Sonnet features which may not be used in the ADS Environment. Major features that do not translate are listed below:
Parameterization and Optimization: Geometry parameters are available in Sonnet, but may not be used in an ADS design. Therefore, parameterization or optimization of a circuit may not be done from within the ADS environment. However, it is possible to translate the ADS design to Sonnet and run a parameterization or optimization in the Sonnet environment, then use the results to change the geometry in ADS to the optimal values.
Reference Planes: You may set a fixed reference plane in the Keysight ADS Interface, but you may not use a linked reference plane where the length of the reference plane is linked to a vertex of a polygon.
The following Sonnet features are not available in ADS: dimensions, subdividers, dielectric bricks, calibration lengths, parallel subsections, and symmetry.
