hive-hwde (Hive-RSI-Lab)ECADConfidence: Medium

Tolerance analysis varies only passive initial tolerances at 25 C, while a real worst-case analysis also needs temperature, aging and active-part spreads like op-amp offset and regulator Vref. The board sim computes feedback and filter corners but never compares them to a constraint window.
