Methodology

Make the method inspectable.

This is CircuitClarity's working reference for how a tool earns its result. It is not a generic credibility statement. Each engine documents its own assumptions and limitations, and an engine-specific rule takes precedence when its physics or intended use demands more care than a general convention can provide.

Deterministic calculations first

CircuitClarity uses stated equations, documented rules, and reproducible numerical methods for a defined design question. Inputs, units, conditions, output precision, and rounding must be visible enough for a visitor to check the work. A calculation that depends on an unknown component curve, parasitic effect, field geometry, proprietary model, or unmeasured environment is labeled as an estimate and bounded accordingly rather than presented as a precise prediction.

Units, notation, and displayed precision

Electrical values use explicit units and engineering notation where it makes a result more readable. Prefixes such as milli, micro, nano, kilo, mega, and giga are never silently changed. Tools distinguish a nominal value from a range, retain enough internal precision to avoid avoidable rounding error, and describe the displayed precision when it affects a component or design decision.

Nominal values are not worst-case behavior

A nominal calculation is useful as a starting point, but it is not a complete design claim. When tolerances, source range, load behavior, temperature, aging, component-series choices, or power dissipation can materially change the outcome, a suitable engine exposes those conditions or tells the visitor that they require further validation. A result should not imply that a nominal value guarantees the same behavior in a physical circuit.

Evidence and source hierarchy

The preferred evidence for a product-specific claim is the relevant manufacturer datasheet. General equations and conventions are checked against authoritative engineering references, standards sources where applicable, and established technical texts. CircuitClarity separates sourced facts from illustrative defaults and from user-entered assumptions. A heuristic can be useful, but it is labeled as a heuristic and is not smuggled in as a universal limit.

Validation before an engine is released

A production engine needs hand-checkable fixtures, invalid-input and boundary tests, unit and sign checks, and a comparison against an independent authoritative example, calculator, or simulator where that comparison is meaningful. Engines that show ranges need tests for their boundary behavior. Warnings and limitations are part of the product logic, so they need tests too, not just prose review.

Where the model stops

CircuitClarity can make early design reasoning more transparent. It cannot certify a circuit, evaluate every parasitic or environmental interaction, substitute for a validated simulation, or confirm safety or regulatory compliance. Use an output as a disciplined starting point and escalate to datasheets, simulation, measurement, and qualified review when the consequence of being wrong warrants it. The Disclaimer explains this boundary in practical terms.
