State minimization

[Altera_Forum]

Hello all. 

 I am wondering if Quartus ii performs any state minimization, and if so, how is it used/enabled?  Thank you

Do you explicitly mean states, or logic?  

State machines are encoded using one of several methods. Grey code, one hot and counter. By default it will encode 1 hot. Minimization can occur during synthesis

Assuming you mean states that cannot be entered, it might depend on the encoding scheme as to whether they are removed or not. The syntheses will remove any redundant logic.
