Hii i am using Modelsim student edition for the simulation of my edge detection code. I am getting the following error.... ** Error: fixed_pkg Unbounded number passed, was a literal used?** can any one please suggest what is the meaning of this error??? Thanx and regards!!

Why would you think anyone will know what's wrong when you didn't include any code?

Very little information to go on: What version of modelsim? what version of fixed_pkg? post some code?

Actually my code is of 877 lines so its not possible to paste the complete code.Also I am having two more modules with it. It is showing error in the following process .. angle1: process (clk) variable index2 :integer:=0; variable index3 :integer:=0; variable count1 :integer:=0; VARIABLE row_cnt_m: INTEGER:=0;--row count VARIABLE col_cnt_m: INTEGER:=0;--coloumn count VARIABLE col_tr_m: BOOLEAN:=FALSE;--end of coloumn begin IF(clk'EVENT AND clk='1') THEN mod_d <= unsigned(to_ufixed(resize((abs(dx)+abs(dy)),7,0))); --Resize the result to 8 bits buffm(index2)<=(mod_d); index2 := index2+1; col_cnt_m := col_cnt_m +1; count1 := count1+1; --at end of one row IF (count1=256) THEN row_cnt_m:=row_cnt_m+1; IF (col_tr_m=FALSE) THEN col_res_m<=col_cnt_m; col_tr_m:=TRUE; END IF; count1 := 0; col_cnt_m :=0; END IF; --at end of one frame IF (index2=65535) THEN row_res_m<=row_cnt_m; row_cnt_m:=0; col_cnt_m:=0; index2:=0; count1 := 0; END IF; IF (row_cnt_m=3) THEN prv_load_m<='1'; cur_load_m<='1'; nex_load_m<='1'; END IF; IF (dx /= "000000000000000" ) THEN IF (dy /= "000000000000000" ) THEN div <= resize((dy /dx),8,-3); END IF; END IF; if ((num1 < div AND div < num2)or( num5 < div AND div < num1) ) then data <= my_lut(4); elsif (num2 < div AND div < num4 ) then data <= my_lut(1); elsif ((num4 < div AND div < num8) OR (num7< div AND div < num6) ) then data <= my_lut(2); elsif (num6 < div and div < num5) then data <= my_lut(3); end if; bufang(index3) <= data; index3 := index3 +1; if (index3 =65535) then index3 := 0; end if; END IF; end process angle1; I am taking a 256 * 256 image.And this is the part for angle calculation in canny edge detector.my_lut is a lookup table having values 0 ,45,90 and 135 in degree.and variable num is different variable range in sfixed formate.

Without all of the signal descriptions, we wont be able to give a full answer. Please attach the full code to your post (dont paste it).

Without your testbench - there is not much I can do as it compiles just fine. I assume your error is runtime?
Debugging is really something you should be doing.

I am trying to debug it from one week.Can you give me outline how to debug a code.And what is this run time error.I am using an small image of size 64 *64.How to deal with run time error.

Run time error is an error that occurs during runtime - ie. during simulation. I do not get a problem compiling your code, but I cannot run your code as I do not have the testbench you are using to simulate it.
