Start With the Basics
Not all parameters are important, or even physically meaningful, for every device or every circuit. Start with the most basic DC parameters, add fixed capacitances, then add parameters for second order effects, if desired. Unspecified parameters default to values that are reasonable for most devices and circuits.
.DATASHEET modeling is available for the following devices:
Device Modeling Procedure
General Procedure
Model Maker accepts an input file that contains .DATASHEET statements, which define the datasheet parameters for a device. You create this input file before you run Model Maker.
The general procedure for device modeling is:
1. Create a file.
2. Enter the .DATASHEET statement, the name of the device, the device type, and any desired parameters:
.DATASHEET <DEVICE NAME> <DEVICE TYPE> <PARAMETERS>
NOTE: The device name can be any alphanumeric string, but you must use the same string to name the file (see step 3) so SPICELink can create a SPICE netlist for DR. SPICE simulation.
3. Save the file with the same name as the device name specified in the .DATASHEET statement, and a .she (sheet) extension. This file is the input file to Model Maker.
4. Put the Model Maker input file in your project directory.
5. Run Model Maker, as described in the following procedure.
Procedure
Double-click on the Model Maker icon.
1. Click on OK. The Model Maker window opens.
2. Select the datasheet model of your choice. Click on OK.
Model Maker generates a filename.mod file and stores it in the local directory.
3. Copy the filename.mod file into the circuit file or include the .mod file into the Spice deck via the Include statement.
