ABSTRACT:
A carry logic circuit for a field programmable gate array (FPGA) which allows a carry input signal to be propagated through the carry logic circuit without passing through a multiplexer of another series connected circuit element. The carry logic circuit uses a function generator of the FPGA to provide a propagate signal in response to first and second input signals provided to the carry logic circuit. Also described are methods for performing a carry logic function in an FPGA.
