Variants

Build(String)

Bad programmatic construction (duplicate name, zero-valued resistor, dangling reference, …).

Unsupported

The deck uses a device the engine does not implement yet.

Fields

name: String

what: String

Elab(String)

The deck could not be elaborated into a circuit.

Singular(String)

Singular MNA matrix (floating node, voltage-source loop, …).

IterLim

NIiter gave up (E_ITERLIM).

Timestep

The transient step shrank below delmin (E_TIMESTEP).

Fields

time: f64

StepLimit

The transient attempted more internal timepoints than Options::max_tran_steps allows — Dune’s guard against runaway breakpoint cascades (D-0022); neither the 3f5 nor ngspice enforces ITL5.

Fields

steps: usize

time: f64

PssConvergence

.pss: the shooting iterations did not bring the period mismatch x(t₀+T) − x(t₀) within tolerance. residuals holds each iteration’s mismatch in units of the tolerance (Pss::residuals). period is the last period iterate of an autonomous oscillator (where T is a Newton unknown); None for a driven circuit, whose period is fixed.

Fields

iterations: usize

residuals: Vec<f64>

period: Option<f64>

UnknownVector(String)

An output selection named a vector the solution does not have.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
