Analog for Digital Engineers Cheatsheet

Dense reference for mechanism-first mixed-signal debugging and architecture closure decisions.

Debug order

diagram

SYMPTOM -> BOUNDARY -> ARTIFACT -> OWNER -> DECISION

LOOPS: bandwidth, damping, peaking, and disturbance transfer
CONVERTERS: aliasing, settling, and metric context validation
NOISE/SI: source-path-victim decomposition and frequency sensitivity
INTEGRATION: boundary contracts, sequencing, and model validity
CORRELATION: setup integrity, model reconciliation, and residual risk

Questions before proposing a fix

Which boundary fails first and is it reproducible?
Which artifact proves mechanism instead of correlation?
Who owns the smallest reversible fix?
What validation and rollback gates close risk?
What residual risk remains and how is it monitored?
