Creating Devices in MDS Using IC-CAP Parameters

You can use extracted IC-CAP parameter values to create devices in the Agilent RF and Microwave Design System, using the DDL script addiccap.ddl. Follow these steps:

1	In MDS, insert and open a file icon for the device to be created.

2	Open the file icon for the system microwave library mwlib and in it open the partition COMPONENTS and, in turn, the partition mns_only.

3	Use the menu command COPY and the mouse to copy the design icon for the device from the partition mns_only to the new file icon window. For example, copy the design icon BJTMODEL or BJTMODELFORM.

4	Rename this design icon, to avoid creating two devices with the same name. For example, add a number to the name, as in BJTMODEL8.

5	In the file icon window, choose the menu command PERFORM > DDL.

6	When the message appears asking for the name of the DDL command file (script), type addiccap.ddl. Then press Enter.

7	When the next message appears, type the name of the IC-CAP file that contains the extracted parameter values (the SPICE deck). Press Enter.

8	When the next message appears, type the name of the model or model form component into which the extracted IC-CAP values will be read. For example, type BJTMODEL8. Press Enter.

The IC-CAP parameters will be used to create a scion of the IC-CAP device in the MNS design icon, using the filename of the IC-CAP parameters. Devices with this name (and the individual device parameters) can now be used like other MDS model elements to create circuit schematics.
