PURPOSE
    Define a formal AI-readable ontology for Integrated Circuits, including
    semiconductor dies, transistors, diodes, resistors, capacitors,
    interconnects, logic cells, analogue blocks, memory, processors,
    mixed-signal blocks, power domains, clock networks, input/output cells,
    fabrication processes, packages, pins, thermal behaviour, timing,
    signal integrity, power integrity, testing, defects, reliability,
    provenance, uncertainty, confidence and recursive integrated-circuit
    reasoning.

CORE_DEFINITION
    An Integrated Circuit is an electronic circuit fabricated as an
    interconnected set of semiconductor devices and passive structures on
    or within a semiconductor substrate, typically packaged as a single
    electronic component.

    Critical Distinction
        Integrated-circuit reasoning must distinguish the semiconductor die
        from the packaged IC, logical function from physical implementation,
        nominal supply voltage from safe voltage range and clock frequency
        from guaranteed operating limits. Process, voltage, temperature,
        revisions, package and test context must remain explicit.

RECOMMENDED_AI_SUMMARY
    An Integrated Circuit combines semiconductor devices, interconnects and
    functional blocks on a fabricated die, normally connected to an
    external system through a package. Reliable IC reasoning preserves die
    and process revision, functional and physical hierarchy, power and
    clock domains, supply voltage, process-voltage-temperature conditions,
    package identity and test provenance while distinguishing logical
    behaviour from physical implementation and functional test success
    from long-term reliability.
