State Machine file

Is there a way to add priority to the transitions drawn in state machine file editor in Quartus Prime Standard/Pro? Say if a state1 has multiple transitions, I want to add priority to the transition ...

    Thank you for your replies. There are some cases where the state machine has to make transition from one state to another based on which condition comes first. I did find a way to work with multiple outgoing transitions, by negating the highest priority condition in the subsequent transitions.

Hi there, State Machine File is an ASCII text file (with the extension .smf) that was originally created for use with Altera's A PLUS and SAM PLUS software packages, which are now obsolete.

It's recommended to edit your RTL files to change the priority.

    The state machine editor in Quartus still creates .smf files that you then click a button to convert to HDL code, so those files are still useful if you want to create a state machine using the GUI.
