Use these drills after completing all topics in ADC / DAC Interfaces. Answer with boundary, mode, metric, artifact, owner, and regression.

Q: Why do directed tests miss converter validity escapes?
A:
They often miss long-run mode transitions and calibration interactions where wrapper assumptions break.
FOLLOW-UP TRAP: Blaming analog core only.[INT][AMS][ADC-DAC-INTERFACES]
Q: What must a sample timing contract include?
A:
Clock relation, aperture assumptions, synchronization boundaries, and acceptable drift/tolerance envelope.
FOLLOW-UP TRAP: Documenting only nominal frequency.BOUNDARY -> MECHANISM -> METRIC -> ARTIFACT -> FIX -> REGRESSIONCONVERTER DATA FLOW
sampling clock -> wrapper -> sync boundary -> system consumerState boundary, mode, and evidence tag with every claim.
Always align analog, digital, and physical owners before signoff decisions.
Fixing averages while tails still fail.
Skipping package/supply evidence in jitter or SerDes issues.
Shipping with waivers that lack owner and expiration criteria.
