Check for this Are there ground parts named 0 (zero) connected appropriately in your design? If not, place and connect one (or more, as needed) in your design. You can use the 0 (zero) ground part in SOURCE.OLB or any other ground part as long as you change its name to 0. Missing DC path to ground This problem applies to analog-only and mixed-signal circuits. If for selected nets in your circuit you see this message in the PSpice output file, ERROR -- Node node_name is floating. then you may be missing a DC path to ground. Check for this Are there any nets that are isolated from ground by either open circuits or capacitors? If so, then add a very large (for example, 1 Gohm) resistor either: ■ in parallel with the capacitor or open circuit, or ■ from the isolated net to ground. Note: When calculating the bias point solution, PSpice treats capacitors as open circuits and inductors as short circuits.
