System Objectives and Trade-offs

Route a system-level design decision to its target, parameter, physics, optimization, and evidence owners.

Node role: Concept.

Reader task: turn a system-level goal into a reviewable set of linked decisions without treating a reusable method as a device-specific objective.

What this page owns

Citation class — engineering choice. This is a cross-project routing convention, not a physical theorem or a universal objective function. The normalization node explains why equal units do not by themselves give quantities equal meanings.

This is a routing node. It owns the distinction between a system objective and the reusable concepts used to discuss it; it does not select a device target, metric, weight, threshold, or trade-off.

The shortest complete route

  1. Put the device-specific goal, boundary, and decision state on a project-owned Design Target.
  2. Reuse parameter meanings and units from source-owner parameter tables; do not define a second table for the same quantity.
  3. Link each physical operand to the exact owning model or quantity resource; use generic Knowledge for the cross-model reasoning.
  4. Record residual scaling, weights, rejection behavior, and evidence provenance in the selected optimization owner’s contract. These are declared choices, not consequences of the physical definition.
  5. Keep exact numerical records in project-owned Evidence, then leave the resulting trade-off for Human review.

Ownership map

Question Canonical owner
What is being designed, and why? Design Target
What does each reusable quantity mean? Parameter Tables and its linked Knowledge node
What physical model and extraction define the quantity? Physics, circuit, or network Knowledge node
How are declared quantities normalized or combined for a search? Auditable Scientific Optimization
What exact result supports the discussion? Evidence registers and renders the record; immutable numerical authority remains in the classified owner-repository artifact
Is the trade-off acceptable? Human review

An objective is not a universal law. A device may legitimately value compactness, bandwidth, loss, tunability, crosstalk, or fabrication margin differently, but each choice must name its target-specific owner rather than silently changing a reusable definition.
