Adding and Editing Properties (Edit Component)
Click Add to add a property to a component definition. In the Add Property dialog box, you can enter the property name, value, and value type (text input, menu, check box, and so on). Depending on the value type, you can also choose a unit type (such as angle, frequency, and capacitance) and the default units (deg, GHz, pF, and so on) for the property. The Value field supports multi-line text which you can add either by pasting, or by direct entry (use Ctrl+Enter to insert carriage returns).
An informational panel provides guidance for entering data in the various fields.
Do not use the names of reserved system parameters for property names.
Click Edit to edit a component property. Editable fields are the same as those described above for the Add Property dialog box.
