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.  

https://www.alteraforum.com/forum/attachment.php?attachmentid=7459  

 

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.
