I am somewhat new to verilog, I tried running this code but it gives me an error:
module enc(in,out);
input [7:0] in;
output [3:0] out;
reg i;
reg [3:0] out;
always @*
begin
for (i=0;i<7;i=i+1)
begin
if ((in[i]==1) && (in[7:i+1]==0))
out = i;
else
out = 0;
end
end
endmodule
I think it complains about in[7:i+1] but i don’t understand why ? Can someone please advise..
EDIT ok so I am reluctant to using the X due to their numerous problems.. I was thinking of modifying the code to something like this :
module enc(in,out);
input [7:0] in;
output [2:0] out;
reg i;
reg [2:0] out,temp;
always @*
begin
temp = 0;
for (i=0;i<8;i=i+1)
begin
if (in[i]==1)
temp = i;
end
out = temp;
end
endmodule
Do you think that will do the trick ? I currently don’t have access to a simulator..
