Wire “floating”, that is connected to a device pin without connection to another pin.Īvoid loops containing voltage sources or inductor, error message: voltage source or inductor loop This error occurs when there is no PSpice model attached to the Capture part or when there’s a Unmodeled pins, error message: Less than two connections at node Very high value resistor, which actually maintains the continuity with the ground reference.Ĭheck that the node has a direct connection with the ground reference. If we want to “simulate” an isolation of a node from the ground, we do it placing a Missing DC path to ground, error message: Node is floating.įor the reasons explained in the previous case, it is necessary to check that no point of the circuit is isolatedįrom the ground reference. It ‘s enough to add the ground reference wherever we wish. This reference point is precisely the ground which must necessarily be present in the circuit. The SPICE algorithm calculates the voltage of each point of the circuit with respect to a reference point, Missing ground, error message: Node is floating. Now let’s see what are the quick solutions to solve the most common convergence issues due to these different types of problems.
