It seem that I can use indifferently <= or = to set an input signal value on my design. Is there a real difference between two ?
dut.button_in = 0
or
dut.button_in <= 0
I have exactly the same output chronogram.

The answer can be found here.
There is no fundamental difference between <= and = except that = can ovewrite the reference and <= is only used for value assignement.
AlexanderSpirin give some examples to illustrate the problem :
Thanks to Vinay Madupura for the clue.
