Reading Extracted Parameters from IC-CAP to MDS

You can access the individual model parameters saved in a SPICE deck, and read them directly into device models in the Agilent RF and Microwave Design System. This is done using the DDL script geticcap.ddl. Note that the model parameters must have been saved using the IC-CAP Save Extracted Deck function. Follow these steps:

1	On the MDS circuit page, insert the model or model form element: for example, BJTMODEL or BJTMODELFORM.

2	Choose the menu command PERFORM/DDL.

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

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

5	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 CMP2. Press Enter.

The IC-CAP parameters will be read in and the model identification field MODEL will have the name that is used as the subcircuit name in the parameter file.

If the collector mounting capacitance appears in the parameter file, it is reported but is not used.
