What version of modelsim?

what version of fixed_pkg?

post some code?

Sorry for less information...I am using model sim 10.4a PE student version.And fixed_package is of $Revision: 1.11 $ version.

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.
