accordance order of LUT pin to Cyclone II pin

I use Quartus II v13sp1 WebEdition. Synthesis is performed for FPGA Cyclone II.

For my diploma work are necessary to know accordance order of LUT pin to Cyclone II pin

what I mean!?

by adding LUT its pins inside of the physical circuit Cyclone II go in order? Like this:

or assigned in a chaotic manner or another principle?

Why it’s important for my research?

I develop the device for which accuracy is critical.

If the legs are in a row, and short circuit, I lose accuracy in the senior ranks - and this is very critical for the result

if if the legs are in a chaotic in a row, and they will short circuit, I lose accuracy in the junior ranks, it is not critical for me!

Thanks in advance for your answers!

    There are no relationship between devices pins and LUT's ports. Also user can't pre-assign any pins to fit with LUT port.
