same constraint, different compiling time

My system has 360 input signal and need to be constraint as clock. I use the following two method to create clock: method 1: create_clock -name {FREQMeasure_ChannleIn} -period 10000.000 -wave...

Hi,

The 360 input signals are unrelated so they won't arrive at the chip at the exact same time. But they never crossing into each other domain.

So I think the two constraints listed above should result into the same result.

Am I wrong?

You are correct. If each domain is independent in the design you can apply one clock constraint to them all.
