 +====== Fidelity Criterion ======

 +
 +===== Discussion =====
 +
 +A Fidelity Criterion specifies an acceptable degree of correspondence between a representation and the characteristics it represents.
 +
 +Within a [[public:99_annexes:annex-b-terms-and-definitions:t:twin_relationship|Twin Relationship]], Fidelity Criteria establish the conditions used to assess whether a [[public:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realization]] represents an applicable characteristic with sufficient correspondence for the intended purpose.
 +
 +Fidelity Criteria may address numerical tolerance, temporal accuracy, behavioral correspondence, state correspondence, completeness, resolution, or other measurable characteristics.
 +
 +Fidelity is purpose-dependent. A Twin Realization may satisfy the Fidelity Criteria for one Test Definition while failing the criteria established for another.

 +  * DIDO-TE normalization of the source concepts
 +
 +===== Note =====
 +
 +A Fidelity Criterion does not require exact equality between a representation and its referent.
 +
 +The applicable Test Definition, Configuration, requirement, or governing source establishes the acceptable level of correspondence.
 +
 +Multiple Fidelity Criteria may apply to the same Twin Relationship.
 +
 +===== Example =====
 +
 +A Test Definition requires a virtual Twin Realization to reproduce a measured pressure value within ±1 percent and within 50 milliseconds of the corresponding real-world observation.
 +
 +The numerical tolerance and timing tolerance form Fidelity Criteria for that test.
