An apparatus for performing phase-lock in a field programmable gate array includes a phase detector configured to determine a phase difference between a carry logic oscillator signal and a reference clock signal; and a combinational circuit coupled to the phase detector, and adapted to function as a variable carry logic oscillator, and further configured to generate the carry logic oscillator signal. A method for performing phase-lock in a field programmable gate array includes: using a carry logic oscillator in a field programmable gate array to generate a carry logic oscillator signal; and determining a phase difference between the carry logic oscillator signal and a reference clock signal.
