After placing a device, the property-dialog window pops up (see page 7.2 ) and demands that you fill in the values. Some properties are required, others are not. There is no complete interactive check as to whether you filled the form in a correct manner or not. So, you should have good knowledge of the SPICE3 syntax, otherwise, you have to use the 'trial and error' method, where 'trial' means netlisting.
Whenever you wish to give a property a parameter instead of a value, you can do that. You can use parameters in expressions, too.
Example:
The first property for the resistor is called 'res'.
You can write
'100k' , '{resparam}'
or
'{wid/leng*sheetres}'.
Specifying the kind of variable by using units like uA, mV , are not allowed.
DON'T USE SI-UNITS IN YOUR EXPRESSIONS !
WARNING: Expressions must not be longer than 40 characters and should not contain whitespaces. Whitespaces are automatically replaced by underscores.
If you want to simulate the schematic later, you need to place a parameter box (see simulation menu) wherein all parameters of all hierarchy levels will be recursively collected. Editing the properties of the parameter box means editing the values of the parameters.
