data type in the current state

i am trying to see my states in the waveform by their names as they are changing, so what i did , i changed the data type in the proparties bar in the waveform for the current state, i changed it to the enum so the changes in the states in the waveform will be changed by their names rather than by state o, 1, 2,..,7 , but as i changed the data type to enum ( just for current state in the waveform) i see the word undifined all the time and simulation result saying node type mismatch..

i am wondering why as the enum has defined the states names in the VHDL codes.

    what simulator are you using?

    are you doing an RTL or post place and route simulation?

    then you cannot see the state names, because they have been removed and replaced with binary state encodings, because it is a post place and route test.

    You will need to do an RTL simulation in modelsim (or similar) to see the state names

    thanks for the reply, i tried with the ModleSim, but i got a message with the license , i am not sure how to solve it, do i need to run the modlesim sepaertely or use quartus
