1. An integrated circuit (IC) device, comprising:

  • a plurality of analog blocks, includingat least one fixed function analog circuit, anda plurality of reconfigurable analog circuit blocks;

    at least one analog routing block reconfigurable to provide signal paths between any of the analog blocks; and

    a digital section comprising digital circuits, wherein each analog block includes dedicated signal lines coupled to the at least one analog routing block and at least one of the reconfigurable analog circuit blocks includes at least one direct signal line coupling the at least one of the reconfigurable analog circuit blocks to an external connection of the IC device without passing through any switch, wherein at least one of the analog blocks comprises a programmable reference block (PRB) configured to generate at least four programmable reference values.
