Enum ErrorSource

    DacQuant {
        input: usize,
        bits: u8,
    },
    AdcQuant {
        bits: u8,

}

A named physical origin of error. The decomposition is user-facing spec: a refusal or a budget report says exactly which arrow of the architecture costs what.

Variants

DacQuant

Half-LSB input quantization of plane input input at bits resolution.

Fields

input: usize

bits: u8

AdcQuant

Half-LSB output quantization at bits resolution.

Fields

bits: u8

WeightQuant

Programmed weights snapped to the unit-element grid — the deviation of the realized configuration from the ideal weights, propagated to the output.

MulInteraction

The Σ εa·εb second-order interaction across all Mul tiles.

EvalRounding

f64 evaluator rounding guard: the behavioral tiers compute in f64, not reals.

TileGain

Per-leg programmed-gain error (programming accuracy + the Pelgrom distance gradient over the PLACED operand separation), at the k·σ envelope.

TileOffset

Per-tile output-referred offset at the k·σ envelope.

Noise

Per-tile sampled-noise floor (kT/C class) at the k·σ envelope.

ThermalGain

Gain drift from the CERTIFIED thermal map’s tile-to-operand temperature gradient (gain_tempco · |ΔT_cell − ΔT_operand|), propagated like any gain error.

ThermalOffset

Output-referred offset drift from a tile’s absolute rise (offset_tempco · ΔT).

CompareBand

A comparator whose certified decision box straddles its ±k·σ input-offset band: the switch may take EITHER branch, so the full branch-hull width is priced — honest uncertainty, never hidden.

ChopResidual

The offset residual surviving the chop average — intra-pair drift over one chop period (the frozen component cancels exactly by construction).

Trait Implementations

impl Clone for ErrorSource

fn clone(&self) -> ErrorSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorSource

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

Formats the value using the given formatter.

impl PartialEq for ErrorSource

fn eq(&self, other: &ErrorSource) -> 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.
