Abstract
One embodiment relates to an integrated circuit including a multiple-voltage programmable logic fabric. The programmable logic fabric includes circuits of a first type operating in a first voltage domain and circuits of a second type operating in a second voltage domain. The second voltage domain has a lower supply voltage than the first voltage domain. The integrated circuit further includes downward level conversion circuit elements in the programmable logic fabric for driving signals from the first voltage domain to the second voltage domain and upward level conversion circuit elements in the programmable logic fabric for driving signals from the second voltage domain to the first voltage domain. Other embodiments, aspects, and features are also disclosed.
