Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements

Let me check this with the engineering team.

Fyi, the engineering team is working on this.

Please do expect that any work involves engineering may takes some time depending on the issue complexity.

May I know are these code for testbench usage?

Not only, we mainly use it in our synthesizable code.

A workaround suggested by the engineering team is to change RTL a little bit.

By changing the assignment of unpacked type to bit by bit instead of complete.

for the given design example

module tb;

enum logic [7:0] {A, B, C} fsm [4];

logic [7:0] state [4];

assign state[0] = fsm[0];

assign state[1] = fsm[1];

assign state[2] = fsm[2];

assign state[3] = fsm[3];

//assign state = fsm;

endmodule

The engineering team will check with the tool vendor on fixing this issue.

@RichardTanSY_Altera Thank you for the follow-up.

The workaround defeats the purpose of these data types, we will wait for the fix.

Do you able to escape the error based on the last email that I sent?

Thank you, please feel free to close the case.

With that, I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.
