 state encoding in Synplify???

I use VHDL and Synplify to describe and synthesize my design, respectively.
when i designed a state machine, I used the attribute of syn_encoding to
specify the type of state encoding, such as "gray".The number of states in
state machine is 20.But when I looked in the log file after synthesis, I
my state encoding had been converted to "one-hot" by Synplify automatically.
Why did it do such? I did not need "one-hot". How could i tell it what I
the state encoding to be?

Any suggestions and replies would be very appreciated!
