Question

Using Verilog, display two words on the Seven Segment Display. For example, if a switch is in the 0 position, it might display the word "happy." If the switch is 1, it should display a different word, like hats.

This is the expected output

Switch OFF: happy

Switch ON: hats

Answer 1

module display (switch , sseg5, sseg4, sseg3, sseg2, sseg1);

input switch;

output reg [6:0] sseg5, sseg4, sseg3, sseg2, sseg1;

parameter h = 7'b1110100;
parameter A = 7'b1110111;
parameter P = 7'b1110011;
parameter Y = 7'b1100110;
parameter t = 7'b1111000;
parameter S = 7'b1101101;
parameter blank = 7'b0000000;

always @(switch)

begin

   if (~switch) begin
       sseg5 = h;
       sseg4 = A;
       sseg3 = P;
       sseg2 = P;
       sseg1 = Y; end
   else begin
       sseg5 = h;
       sseg4 = A;
       sseg3 = t;
       sseg2 = S;
       sseg1 = blank; end
end

endmodule
