Digital twins are not automatically authority.
That is the next problem in semiconductor realization.
Digital twins, fab twins, package twins, EM models, PDN models, thermal models, and AI-assisted simulations are becoming essential because modern systems are too complex to validate only through physical trial-and-error.
But a model output is not the same as decision authority.
A simulation may predict acceptable thermal behavior, but real TIM thickness, lid attach, airflow, workload burst, or board interaction may change the result.
A PDN model may pass under nominal assumptions, but package inductance, decoupling placement, VRM response, silicon switching current, and thermal drift may create real droop.
An EM model may show margin, but package escape, return path, connector transition, crosstalk, jitter, and voltage noise may reduce the field result.
The next step is not just more simulation.
The next step is governed system realization:
model fidelity
measured evidence
CTQs
uncertainty
causality
lifecycle feedback
bounded decision authority
Digital twins model the system.
Governed System Twins determine whether the model-supported evidence is mature enough to support a real decision.
