# Interconnect propagation and length matching
# Scope: Quasi-TEM delay using supplied effective dielectric constant.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 100 mm
effectivePermittivity = 3
lightSpeed = 299792458 m/s

delay := length*sqrt(effectivePermittivity)/lightSpeed [ns]

check delay budget: delay <= 1 ns

scenario alternative: length = 80 mm
