IC with first and second functional circuits coupling only first circuits to output bond pads

An integrated circuit comprising:

• (a) a substrate of semiconductor material having a core area and a peripheral area;
• (b) bond pads formed in the peripheral area, the bond pads including first and second input bond pads and an output bond pad;
• (c) a first set of one or more programmable digital logic transistor circuits formed in the core area, each programmable digital logic transistor circuit of the first set having a first programmable function, each programmable digital logic transistor circuit of the first set having respective first and second inputs coupled to the first and second input bond pads respectively, and having a respective output coupled to the output bond pad;
• (d) a second set of one or more programmable digital logic transistor circuits formed in the core area, each programmable digital logic transistor circuit of the second set having a second programmable function different than the first programmable function, each functional programmable digital logic transistor circuit of the second set having respective first and second inputs and having a respective output;
• (e) conductive material coupling the first and second input bond pads to the respective first and second inputs of the one or more programmable digital logic transistor circuits of the first set and coupling the output bond pad only to the respective output of the one or more programmable digital logic transistor circuits of the first set;
• and
• (f) control circuitry for programming the first set of one or more programmable digital logic transistor circuits and the second set of one or more programmable digital logic transistor circuits.
