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...

The 360 input signals are unrelated and they never crossing into each other domain.

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

In fact, they output the same result actually.

But what confused me is why there exist so large compiling time different between them.

Thanks for you response!
