Altera 5CGXFC3B7U15C8N delay time of a single cell?

Hello, I am quite now in the world of the FPGAs. I would like to ask what is the delay time of a single inverter of an Altera 5CGXFC3B7U15C8N FPGA! I am trying to find some information in...

There are luts that can be used for inverters, or any other gates.

But your ring oscilator is not going to be very reliable on an fpga - it will be highly affected P&R and PVT. You can hand control the placement to get a reasonable level of control, but temperature will just affect the output/

My purpose is to measure the temperature changes based on this R.O., so, in that case do you suggest using LUTs or Gates?
