this is my code for fir filter.i want write the output in "to_file" text file.

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;

entity output is

end output;

architecture Behavioral of output is

writefp(comp_line,y);
writeline(to_file,comp_line);
end process p1;

end Behavioral;

this is my code for fir filter.i want write the output in "to_file" text file.but following error is occured.
ERROR:Xst:1914 - "C:/Xilinx92i/fir/output.vhd" line 80: File <to_file> does not exist.

pls help me to solve this error.

Hi ketanlad_18,

One thing i noted is that here the error occurred is at line number 80 which is not there in the above code.... (from beginning to the end Behavioral the lines may be less are less than 80)

You cannot run this code through XST because it is a testbench. You need to run it with the ISE simulator. XST is a synthesisor and this code is not suitable for synthesis (so you cannot run it on a chip)

On your code:
1. Your process will loop forever at 0 time. You either need a sensitivity list or some wait statements in there.
2. what is the writefp() procedure? it is not a standard one.

can you please give me the vhdl code for FIR filters.

How much are you willing to pay?

Your contextless thread hijack calls for random google hit #2.

There you go:

It's FIR, it's VHDL code, all per your detailed requirements. Problem solved, right? What's that you say, you cannot use this code? Oh however can this be, since it totally conforms to your detailed specs?
