The model statement specifies the name of your RF device model, in this case, MyNewRFBJT. The symbol statement determines the device type and schematic symbol. The symbol_name can only be one of the choice given in the table below. The frequency units can be hz, khz, mhz or ghz. "s" implies the s-parameters. If the complex_data_format is left blank, the S-parameters are interpreted to have Mag/Phase format, with the magnitude on a linear scale and phase expressed in degrees. The other options for complex_data_format are "ma" for magnitude expressed in dB, or "ri" for Real/Imag format. The last part specifies the reference impedance value, which must come after letter "r". In the above example, the reference impedance is 50 Ohms.

When creating a new simulation model as will be discussed later, you can also instruct the Device Editor to create a default (simple and basic) symbol for a it. Normally, if you have already set the simulation model pin or terminal names, the symbol pins will automatically match the model pins. In many other cases, you may create the models and symbols separately and independently. In such cases, you need set and match the symbol pins with the corresponding model pins.
It is important to match up the pins correctly because the simulator will need this information to be correct to simulate the part correctly. Limit pin names to 10 characters or less. For spaces use underscore ( _ ). Dashes are not accepted. Click OK when all the pins have been matched up correctly.

==Creating a New Device from an Existing Simulation Model==
If your circuit contained XSpice parts, you will have to designate whether the pin is digital or analog. If the pin is Digital, then you must also designate whether it is an Input or Output pin. If the pin is Analog, then input and output direction designation do not apply. Click accept when you're done with each pin. Click OK when you're done setting the pins.
For Digital parts, Select and edit the [[Digital Simulation|digital simulation]] model you just created. In the Edit Simulation Model dialog box, click the Edit Pin Properties button to access the list of digital pin. You should set each pin's direction, state, and propagation delay. Click the Accept button to accept changes and move on to the next pin. Refer to the Database Editor Menu's Edit simulation model section for more information.
Once you're done setting the pin properties, close all the dialog boxes. All that remains is to alter the symbol if you want to rearrange the symbol pins and exit the Database Editor. In the Workshop pull up your new part and use it like any other part.
