To measure internal delays in circuits

Hi, I want to measure the internal delay of gates using FPGA hardware and compare the propagation delays of several circuits such as ripple-carry and carry-lookahead adders. I want to measure the...

You might be best doing this using time quest. Set it up with registers at the input and output of the adder then use time quest to analyse the timing. This will remove the extra delay added to route the signals in and out of the chip.
