What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
Reduced to a checklist, the practice above resolves into five concrete questions that separate a package that will ship reliably from one that merely simulated well. First, what KGD screening — electrical and thermal — was each chiplet actually run through, and at what confidence does that screening estimate its ? Second, what bond pitch and alignment tolerance does the chosen joining method require, and has that tolerance been demonstrated on this specific stack rather than assumed from a vendor’s best-case roadmap figure? Third, has cross-vendor interoperability — where that applies — been proven on a compliance bench, not merely inferred from both parts individually passing spec…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
