Creating Designs for Simulation
and Board Layout
When creating designs for both simulation and printed
circuit board layout, some of the parts you use will be for
simulation only (for example, simulation stimulus parts
like voltage sources), and some of the parts you use will
have simulation models that only model some of the pins
of the real device.
Those parts that are to be used for simulation, but not for
board layout, will have a SIMULATIONONLY attribute. To
see an example of this, double-click a VDC voltage source
to bring up the Attribute Editing dialog box.
You can add this (or any) attributes to your own custom
symbols.
Specifying Part Attributes
1 In the symbol editor, select Attributes from the Part
menu to display the Attribute Editing dialog box.
2 Double-click the Name text box and type
SIMULATIONONLY.
3 Click Save Attr.
4 Click OK.
For more information on defining attributes on part
symbols, Refer to Defining Part Symbol Attributes in the
Creating Symbols chapter of your PSpice user’s guide.
