Using an Existing Sonnet Substrate

To use an existing Sonnet Substrate File for your design which you will be simulating using Sonnet, select Sonnet ⇒ Setup ⇒ Tech. File ⇒Load Substrate File from the menu of the Layout window. A browse window appears which allows you to select the desired “.matl” file. These settings are loaded into your design. For information on creating a Sonnet substrate file, see "Saving a Substrate File" on page 93.

You may also use an existing Sonnet Substrate file or ADS Substrate by clicking on the buttons at the top of the Setup Substrate File window as shown below. The function of the buttons is shown in the table following. After every button entry is the equivalent menu command. Note, however, that clicking on a Load button will load the parameters from the source, but does not save the substrate information. Using any of the update commands, loads the parameters and saves them in a .matl file.
