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...

Why do you need to know a propogation delay through a design? you realise that this delay can vary from chip to chip, build to build and with temperature, so you wont get a very reliable measurement.

If you have a synchronous design you can provide timing specs to timequest and it will check to see if your design meets those specifications.
