Error Messages

Not enough memory for this operation

The CircSolver application is not able to allocate enough memory to complete the current action. Closing other documents or applications may correct this situation.

Two or more Components are using the name : "X"
Two or more Circuit Tags are using the name : "X"
Two or more Circuit Tools are using the name : "X"
A Circuit Tag and a Component are using the name : "X"
A Circuit Tool and a Component are using the name : "X"
A Circuit Tool and a Circuit Tag are using the name : "X"

These errors tell you that two or more objects have been given the same name, "X". Changing one of the object's names will eliminate this error.

Resistor "X" has null value
Capacitor "X" has null value
Inductor "X" has null value

All passive components must have a nonzero value.

Voltage Source has no valid name
Current Source has no valid name
Voltage Tag has no valid name
Current Tag has no valid name

All independent sources and circuit tags must have a valid alphanumeric label.

Dependent Voltage Source "X" has an erroneous dependency equation
Dependent Current Source "X" has an erroneous dependency equation

This error tells you that a dependent source has a zero value in the denominator of its dependency coefficient.

Voltage Tag "X" is undefined
Current Tag "X" is undefined

Voltage and Current Tags must be attached at both ends to other components in the circuit.

Current Tag "X" is not associated with a single passive component

Current Tags must be attached to the ends of a single passive component.

The Circuit has no Independent Sources

All circuits must have at least one Independent Source, else the circuit will have no input.

Voltage Source "X" is directly shorted or is not loaded
Current Source "X" is directly shorted or is not loaded
Dependent Voltage Source "X" is directly shorted or is not loaded
Dependent Current Source "X" is directly shorted or is not loaded

If a voltage or current source is shorted, or is not loaded then the circuit will have no valid solution.

Two or more Voltage Sources are shorted together

If two Voltage Sources are directly connected at both ends, then there will be no way to determine the voltage of either source and the circuit will have no valid solution.

Essential Branch has more than one current source

If a single branch has more than one Current Source, then the current in the branch will be undefined and the circuit will have no valid solution.

Essential Node has a current source in every branch

If a single node has a Current Source in all of its branches, then the current entering or leaving the node will be undefined and the circuit will have no valid solution.

The Components do not make a valid circuit

CircSolver will report this error if it is unable to form a valid solution matrix for the circuit.

This error may be reported if the circuit has unconnected current loops. If so, then you can eliminate this error by connecting the loops with a wire stretched between a node in each loop, or by attaching a ground connection to one node in each loop.

Incorrect equation syntax

This error tells you that the a Transfer Function's output equation has an incorrect arithmetic syntax.

User Interrupt

The user clicked the Cancel button before the circuit compilation was completed.
