Analysis Setup

Next you will set up the analysis controls for the template file. These analysis controls will be imported from the template during the translation.

51.  Select Circuit ⇒ Settings  from the project editor main menu.

The Circuit Settings dialog box appears on your display. You may also open this dialog box by clicking on the Settings button on the tool bar.

52.  If it is not already selected, click on the Sweeps entry in the side bar menu of the dialog box.

The appearance of the dialog box is updated and now displays the Frequency Sweeps.

The analysis will be an ABS sweep from 0.3 to 30 GHz. For more information about ABS sweeps, please see Adaptive Band Synthesis (ABS) in the Sonnet User’s Guide.

53.  If it is not already selected, click on the Analyze with Sweeps radio button.

Selecting that radio button enables the controls on this page and uses the sweep sets entered here to control the analysis.

54.  Click on the Add Sweep Set button .

The appearance of the dialog box is updated and displays Sweep Set 1. The checkbox next to the sweep set is selected to indicate that it will be used during the analysis.

55.  Click on the down arrow next to the green plus sign and select Adaptive Sweep (ABS) from the pop-up menu.

The appearance of the dialog box is updated with the entry fields for an ABS sweep, which is also selected by default.

56.  Enter “0.3” in the Start text entry box and “30” in the Stop text entry box.

This defines the ABS analysis band.

57.  Click on the Em Options entry in the side bar menu.

The appearance of the dialog box is updated with the Em Options page.

58.  Click on "Advanced Options, Subsectioning and ABS" in the dialog box.

The appearance of the dialog box is updated to show the Advanced Options tabs.

59.  If it is not already selected, click on the "Advanced Options" tab, then select the Q Factor Accuracy checkbox in the Settings Options dialog box.

This option increases the accuracy of the Q factor when ABS is used. Normally ABS uses only S-parameters to determine convergence. When this option is used, ABS uses both the S-parameters and Q-factor for convergence criteria.

60.  Click on the OK button to close the Circuit Settings dialog box and apply the changes.

This completes the setup of the analysis controls.

61.  Select File ⇒ Save As from the project editor main menu.

This completes the setup of the template file, so you need to save the project for use in the import. A browse window appears on your display.

62.  Save the file under the name “my_gds_template.son” in your working directory.

Once you have completed setting up your template file, you are ready to import the GDSII file.

63. Select File ⇒ Close Project from the main menu.
    
    The project is closed and the Edit tab is removed from the session window.
