Analog pad
Maturity plannedTargets ASIC (CMOS) onlyDifficulty MediumPriority 1
Low-resistance, low-capacitance analog pass-through pad with dual-diode ESD and optional series resistor, for ADC inputs and bias pins.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
