metastable example of verilog

Question

I'm learning metastable and using 2-FF sychronizer . And I.m trying to figure out it meaning.

but it seem to almost example is about click button and cause it so we need 2-FF sychronizer to solve it.

Is there any other example code of verilog that I can try to test on my own computer?

I think it will more understandable and compare 1-FF and 2-FF by result.

thanks all.

Metastability is the result of analog behavior. You cannot simulate metastability problems with a digital event driven simulator. You can only verify that the solution doesn't cause other functional issues. CDC/RDC tools can help statically (i.e. without dynamic simulation) catch design flaws where metastability might arise and make sure they have been properly corrected
