Abstract:
1. A programmable device comprising: a first input node having a first voltage value responsive to at least a first input voltage, wherein the first input node is connected with an input device; a second input node having a second voltage value responsive to at least a second input voltage, wherein the second input node is connected with the input device; a first programmable voltage module connected with the first input node, a second programmable voltage module connected with the second input node, wherein the second programmable voltage module is adapted to provide a second compensating voltage to the second input node; and a plurality of programmable logic resources adapted to implement functions of a logic circuit and to evaluate the first and second voltage values, wherein the functions include providing the first signal to the first programmable voltage module and providing a second signal to the second programmable voltage module, wherein the first and second signals specify values for the first and second compensating voltages.
