Troubleshooting for the circuit configuration¶
This is the troubleshooting for cases where there is a problem with the circuit configuration.
No Source error¶
[TOPOLOGY_NS]
Failure
This is an error that occurs when no power source or LC part exists. An analysis cannot be performed on a circuit in which no energy source of the circuit exists. Please place and connect a power source or an LC part in the circuit. Note that if it is a circuit with programs only, such as with PRC parts, the analysis is possible.
Illegal Connections LC error¶
[TOPOLOGY_ICLC]
This is an error that occurs when an LC part has an invalid connection.
When a capacitor is the cause
A parallel connection of a voltage source and a capacitor is invalid in the calculation and may cause an error.
When you want to make such a connection, check Enable ESR in the spec section of the capacitor [Capacitor] and
set the equivalent series resistance [ESR].
When an inductor is the cause
A series connection of a current source and an inductor is invalid in the calculation and may cause an error.
When you want to make such a connection, explicitly insert a large resistance in parallel with the inductor [Inductor].
A connection line is not properly connected
When a connection line is not properly connected, an error may occur.
Connection lines that are not connected are displayed as dotted lines, so please check them before running the simulation.
Note that all parts that are not connected are regarded as being connected to the ground terminal.
Invalid connection of an LC to a transformer or an operational amplifier
Because transformers and operational amplifiers are ideal parts, the way a capacitor or an inductor is connected, for example connecting them to both ends of a transformer, may result in an invalid connection in some cases. Please add a resistance that does not affect the circuit characteristics in series with a capacitor, or in parallel with an inductor.
An L is directly connected to a diode
If the simulation speed becomes extremely slow, add a high resistance in parallel with the directly connected inductor
A circuit with parallel connections of C, series connections of L, or a large number of Cs and Ls
The number of capacitors and inductors affects the simulation speed.
Avoiding parallel circuits of capacitors and series circuits of inductors, and combining them into a single capacitor or inductor, leads to an improvement in the simulation speed.
Regarding inductors, even if they are in separate places they may form a series circuit of inductors, so looking at the circuit broadly leads to a resolution of the error.
