Floating Point Calculation MegaWizard

Hi Guys,

i am interested to use floating point calculation megawizard - altfp_add_sub. the implantation was done in the standart way, but result wasn't the same.

according user guide the entity has to be as in the attachments:

The only thing that I change in MegaWizard GUY is single precision.

But I get somthing other like this:

aclr :in std_logic;

clk_en :in std_logic;

clock :in std_logic;

data :in std_logic_vector(25 downto 0);

distance :in std_logic_vector(4 downto 0);

result :out std_logic_vector(25 downto 0);

This behavior is checked in Quartus 9 and Quartus 12

In addition I would like to say that there is no device in "device family" check box and the entity name of Mega Wizard has been changed, for example:

entity Floating_Point_Add_altbarrel_shift_35e is

.....

when I chose only "Floating Point_Add" to be the entity name.

Will be glad for any support in this term.

TNX
