LM_LICENSE_FILE environment variable is set correctly and I can see the simulation result but the output is unkonwn(XXXX).

ls138.v

module ls138(G1,G2A,G2B,A,Y);
input G1,G2A,G2B;
input [2:0] A;
output [7:0] Y;
reg [7:0] Y;
always@(G1 , G2A , G2B , A)
begin
if(G1&&(!G2A)&&(!G2B))
begin
case (A)
3'b000: Y<=8'b1111_1110;
3'b001: Y<=8'b1111_1101;
3'b010: Y<=8'b1111_1011;
3'b011: Y<=8'b1111_0111;
3'b100: Y<=8'b1110_1111;
3'b101: Y<=8'b1101_1111;
3'b110: Y<=8'b1011_1111;
3'b111: Y<=8'b0111_1111;
default: Y<=8'b1111_1111;
endcase
end
else
Y<=8'b1111_1111;
end
endmodule

simulaotion result is attached.
