Enum SolverMethod 

pub enum SolverMethod {
    NewtonRaphson,
    WrightOmega,
    EbersMoll,
    GummelPoon,
}

Preferred nonlinear solver method for a component.

Components that support explicit (closed-form) solvers return SolverMethod::WrightOmega from solver_hint(). The compiler build pass uses this hint to select the appropriate root type.

NewtonRaphson is available as an explicit override for debugging or for circuits where the explicit solver needs to be compared against the iterative solver.

Variants

NewtonRaphson

Newton-Raphson iterative solver (default for all nonlinear devices).

WrightOmega

Wright Omega explicit solver (closed-form, no outer NR loop). Faster than NR for diodes; equivalent audio quality.

EbersMoll

Simplified Ebers-Moll BJT model (fast alternative to Gummel-Poon).

Omits Early effect, high-injection knee currents, leakage, and parasitic resistances. Uses only IS, BF, BR, NF, NR from the model. Approximately 3× faster per NR iteration than GummelPoon.

Suitable for clean amplifier stages where GP advanced effects are negligible at the operating point.

GummelPoon

Full Gummel-Poon BJT model (default for BJTs).

Includes Early effect, high-injection, leakage, and parasitic resistances. More accurate but more expensive per NR iteration.

Trait Implementations

impl Clone for SolverMethod

fn clone(&self) -> SolverMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SolverMethod

impl Debug for SolverMethod

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

Formats the value using the given formatter.

impl Default for SolverMethod

fn default() -> SolverMethod

Returns the “default value” for a type.

impl Eq for SolverMethod

impl PartialEq for SolverMethod

fn eq(&self, other: &SolverMethod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
