helo members ,

i get this warning in questasim ,

Warning: NUMERIC_STD.">=": metavalue detected, returning FALSE,
here count is unsigned vector ..
1
for i in 0 to 2 generate

2
process(clk,rst)

3
 if(rst)then

4
   count<=<=(others=>(others=>'0'));

5
 elseif rising_edge(clk)then

6
  if((count(i)>=to_unsigned(0, count(i)'length))

7
..

8
 end if;

9
end if;

10
end process

11
end generate

how can this be solved. i assigned initial values dueing signal count 
initialisation and during reset still gettind same error

Whats that?

The problem may be located somewhere outside the posted code snippet. 
Very interesting are the first 5 lines of your VHDL code. So simply 
attach your VHDL file as a *.vhdl file.

In such case I change the simulator runtime options (see graphic).
The simulator will stop an show the relevant code line.
