Parameter Property: Property Number 3

The param property specifies the part of the device SPICE line which provides an initial condition or other data not included in a model or value string. The property is normally applied to device and subcircuit instances with the Properties command, or to cells with the Cell Properties command. When applied to cells or subcircuit instances, the property is used to provide parameter definitions for SPICE (see the description of the .subckt line in the WRspice manual). This can also appear in the device definition in the device library file to provide a default. If given to a cell, instances of the cell will inherit the property, which can then be changed from within Xic on a per-instance basis. For device instances, this property specifies any parameter, such as device area, which is provided in the device line after the model. This manifestation was referred to as the initial condition (``initc'') property in previous documentation.

5 3 string;
The string will be appended to the device line when a SPICE file is created. It can contain initial condition data or other parameters significant to the device, which are syntactically expected to the right of the model or value.
