Problem with assigning value to a net

[rohankewl]

I'm getting the following the error message.
Please help me fix it.
Error: C:/Modeltech_xe_starter/examples/mph.v(45): (vlog-2110) Illegal reference to net "out".
** Error: C:/Modeltech_xe_starter/examples/mph.v(61): (vlog-2110) Illegal reference to net "out".

I have declared out as output[2:0] out
and in always block
I have the two statements where it is showing the error
out =3'b000;
out= mem[ptr];

(vlog-2110) illegal reference to net

hi,

When assigning a value to a net, you cannot use the following type of
assignment statement:
out = 3'b000;

This will result in an "Illegal reference to net" error message.
Instead, if you want to make several assignments to a net, do something
like the following:

// An example in test bench

reg [2:0] out_tmp;
wire [2:0] out = out_tmp;
initial begin
...
out_tmp = 3'bzzz;
...
out_tmp = 3'b000;
...
end


Hope it helps.

output reg [2:0] out;

illegal reference to net

if inside always block. use reg type, and out <= ... (other wise, blocking statement)
other wise, use assign out = ....
