The characterized non-ideality figures a physical target carries.

Fields

weight_gain_sigma: f64

Fractional 1σ error of a programmed weight (unit-element/programming accuracy class).

gm_distance_sigma_per_pitch: f64

Additional fractional 1σ gain error per tile-pitch of operand separation — the Pelgrom distance-gradient lever the placer optimizes against.

offset_sigma_v: Volts

Per-tile output-referred offset 1σ, volts.

noise_floor_v: Volts

Sampled-noise floor (kT/C class), volts rms, per tile.

cross_tier_gain_sigma: f64

Additional fractional 1σ gain error between tiles on SEPARATELY MANUFACTURED tiers — a flat categorical ceiling, not a distance gradient: dies do not share a Pelgrom field, so cross-tier matching gets the class figure, full stop.

gain_tempco_per_k: f64

Fractional gain drift per kelvin of TEMPERATURE DIFFERENCE between a tile and its operand tile — matching cares about gradients, so the coupled term prices |ΔT_cell − ΔT_operand|, not absolute temperature.

offset_tempco_v_per_k: f64

Absolute output-referred offset drift, volts per kelvin of a tile’s rise.

chop_residual_v: Volts

The per-tile offset RESIDUAL after chopping, volts 1σ — intra-pair drift over one chop period (the frozen component cancels exactly; this is what survives).

provenance: &'static str

Sourcing statement — pinned verbatim by analog_provenance_lock.

Trait Implementations

impl Clone for NonIdealityModel

fn clone(&self) -> NonIdealityModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonIdealityModel

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

Formats the value using the given formatter.

impl PartialEq for NonIdealityModel

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