Most of the components from the SystemVision component library allow you to specify property values (parameters) that will overwrite the default values. Some components like resistors, capacitors, inductors, and a few others, require that you add values.
Components that require you to enter property value(s) will be highlighted with a red outline.
After placing a component on the schematic, enter property values as follows:
Double-click on the component to bring up the Property Editor.
Right-click on the component and select Properties.
Once the Property Editor comes up, you can type in desired values. Empty fields that require values will be highlighted.
