ABSTRACT:
Internal net drivers of a field programmable gate array are laid out with additional transistors to increase current drive capability at low supply voltages when a low supply voltage mask option is used. When a high supply voltage mask option is used, the additional transistors are not used in this way and the net drivers do not provide additional switching current drive capability. In some embodiments, were a low supply voltage mask option net driver operated at the high supply voltage, an impermissibly large switching current would flow through a programmed antifuse in a net coupled to the output of the net driver.
