syn_encoding attribute vs STATE_MACHINE_PROCESSING

[Amiga]

Hi all,

In specifying the encoding method for a state machine, which has priority, the syn_encoding attribute or Quartus' STATE_MACHINE_PROCESSING?

From my research, it seems that Quartus' option takes priority.

If So, in order to enable syn_encoding, do I need to change STATE_MACHINE_PROCESSING to User-Encoded?

Thanks,

Yes, you are right. Assignments or settings made with the Intel® Quartus® Prime software, the .qsf, or the Tcl interface take precedence over assignments or settings made with synthesis attributes in your HDL code. 

You can use the User-Encoded setting of the State Machine Processing option, to assign your own state encoding.
