Programmable analog and digital input/output for power application

A programmable logic device (PLD) comprising:

• a threshold comparator block;
• a programmable fabric comprising a digital fabric and an analog fabric;
• and
• a signal wrapper configured to provide signals between the threshold comparator block and the programmable fabric;
• and
• input/output (I/O) pins configured to interface analog and digital signals between the threshold comparator block and the programmable fabric via the signal wrapper,
• wherein the threshold comparator block comprises:
• an interface to the programmable fabric of the PLD via the signal wrapper;
• and
• one or more signal comparators configured to receive two analog input signals from the analog fabric of the programmable fabric and provide a digital output signal indicating a comparison result of the two analog input signals to the digital fabric of the programmable fabric,
• wherein the threshold comparator block is configured to interface with one or more adaptive blocks integrated in the PLD via the programable fabric and the signal wrapper.
