Product Enhancement Suggestion

[TuckerZ]

Hello, 

I would really like to see Quartus implement all of the "selection statement" functionality described in IEEE 1800-2017, Section 12.5. I tried to use a case-inside statement and Quartus does not support that feature of the language. 

Thanks,

Tucker Zischka

Hi Tucker,

Thank you for the feedback. I will file a enhancement to the developer regarding this.

May I know if it is possible to attach small test case in qar for this cases?

Hello, 

What do you mean by a test case in qar for this cases? 

Thanks,

I mean a small design that replicable to be used as test case showing the unsupported feature

Here is a snippet of code: 

package command_pkg;

typedef enum logic [2:0] {
    op1,
    op2,
    op3,
    op4,
    op5,
     op_null
} operation_t;
end package

module command
    import command_pkg::*;
    (
        input wire [7:0] cmd_decoded, 
        output operation_t command_details
    ); 
     always_comb begin
        case (cmd_decoded) inside
                8'b????1101:
                    command_details = op1;
                8'b????1001:
                    command_details = op2;
                8'b????1110:
                    command_details = op3;
                8'b00000000:
                    command_details = op4;
                8'b????0110:
                    command_details = op5;
                8'b????0111:
                    command_details = op_null;
                8'b????0100:
                    command_details = op_null;
                default: begin
                    command_details = op_null;
                end
        endcase
    end
endmodule

Tucker,
