Troubleshooting for numerical calculation

This is the troubleshooting for cases where there is a problem with the numerical calculation.

Numerical Problem error

[NUMERIC_NP]

Note

The pop-up that reports a Numerical Problem error may contain an error number.
This is a value for identification, and please note that it does not specify the countermeasure described below.

When the circuit configuration is invalid

This may occur when there is a problem with the circuit configuration. Refer to Errors related to the circuit configuration and correct it.

An error related to the number of states has occurred

When an error related to the number of states occurs, a Numeric Error may occur. Refer to Errors related to the number of states and correct it.

In the case of a large-scale circuit

In a circuit with a large-scale configuration, or a circuit in which similar circuits are connected in parallel, a numerical error may occur when it contains many LCs (for example, a total of about 50 to 100 LCs). This does not mean that an error always occurs when many LCs are included. In this case, please remove extremely small LCs, divide the circuit into partial circuits, and so on.

Internal Calculation error

[NUMERIC_IC]

An error related to the number of states has occurred

When an error related to the number of states occurs, a Numeric Error may occur. Refer to Errors related to the number of states and correct it.

Extreme parameters are set

When a parameter that is extremely large or extremely small compared with the parameters of the other parts in the circuit (ex: R = 1uΩ, L = 1pH, C = 1pF) is set, a numerical error may occur. In this case, please correct the circuit so that extreme parameters are relaxed as much as possible, for example by deleting a part whose value is small enough to be ignored, or by regarding a large value as an open circuit.
