Introduction to OrCAD PSPICE
1. All circuits must have a reference node. In PSPICE, this node is usually marked with the
number “0.” Note: The conventional OrCAD ground symbol is not appropriate for
3. All components must have a value. The following suffixes are used to modify values:
4. All components must have a unique designator. For example, there can’t be two instances
of a component reference “R1” within the same circuit.
5. There must be no space between a number value and its modifying suffix. For example,
the value “1 k” for a resistor or “1 V” for a voltage source will cause an error.
The correct way of specifying these parts is “1k” and “1V” (upper and lower case make no
