Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements - Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements module tb; enum logic [7:0] {A, B, C} fsm [4]; logic [7:0] state [4]; assign state = fsm; endmodule Never had an issue with Vivado and never had an issue with Modelsim: https://www.edaplayground.com/x/S3Va With Quartus Pro 22.2, I get Error(16983): arrays have different elements I believe this should be allowed by the specs.

Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements Thank you, please feel free to close the case. Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements Yes, there is a plan to fix this but it may takes time and I do not have the exact detail on when it will be fix. As this is subject to change. Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements Can we expect this to be fixed in a new release? Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements Do you able to escape the error based on the last email that I sent? Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements @RichardTanSY_Altera Thank you for the follow-up. The workaround defeats the purpose of these data types, we will wait for the fix. Regards, Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements 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. Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements Not only, we mainly use it in our synthesizable code. Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements May I know are these code for testbench usage? Replies: Re: Quartus Pro 22.2: enum logic vs logic : Error(16983): arrays have different elements 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.
