I have used Quartus II 14.1 (64-bit version).
I made a mod 3 asynchronous counter as Fig 1.
The functional simulation issues the error message as Fig 2.
And, the timing simulation result is weird.
I expect the result sequence is 00->01>10->(temporally 11)->00->01->........
But, the result is weird as Fig3.
Is this a simulator bug? Or, let me know what is a part of mistake.
Th higher version of Quartus II 14 is as the same.
Thanks,
Ed
