Project Options
This section of the Options dialog box allows you to select the Compute Currents and Q-Factor accuracy run options and access the Advanced Run Options dialog box. 
Select the Compute Currents checkbox in the Options dialog box to compute current density data during your analysis. This run option outputs current density information for the entire circuit which can be viewed using Sonnet’s Current Density Viewer. Be aware that for an adaptive sweep, current density data is only calculated for discrete data points and this option is not available for a DC Point sweep.
For instructions on how to open the current density viewer, see Current Density Viewer.
When performing an ABS sweep, there is an option to increase the accuracy of the Q-Factor. The Q-Factor is the quality factor of the project and is calculated using this formula:
Selecting this option increases the accuracy of the Q-factor when ABS is used. Normally ABS uses S-parameters to determine convergence. When this option is used, ABS uses both the S-parameters and Q-factor for convergence criteria. This option should be used whenever you plan on viewing/calculating Q-factor, but could require more discrete frequencies.
There are a number of advanced run options available in the Sonnet Advanced Project Options dialog box. This dialog box is accessed by selecting the Advanced button in the Project Options section of the Options dialog box. You may also open this dialog box by selecting Sonnet ⇒ Setup ⇒ Options ⇒ Advanced Project Options.
The Sonnet Advanced Project Options dialog box allows you to select additional run options. By default, the De-Embed option is on, and all other options are off. To turn on an option, click on the appropriate checkbox. For information on any of the available options, please see the Advanced Options in the project editor.
If you wish to add any notes or comments to your design, you may enter them in the Sonnet Project Comments entry box. The comments are saved in your project by the Keysight ADS Interface.
