Floating Point Calculation MegaWizard

Hi Guys,

I am interested to use floating point calculation megawizard - ALTFP_ADD_SUB.

The only thing that I change in MegaWizard is single precision but I'm getting 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 ut std_logic_vector(25 downto 0);

This behavior is checked in Quartus 12

In addition I would like to say that 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.

Thnak's

    Found the problem!

    For some reason, the name that I gave to the entity ("Floating Point_Add") was hidden at the end of the " Floating Point_Add.vhd" file (inside "Floating Point_Add.qip"). to get to him, you simply need to scroll down to the end of the file (at the beginning of the file the " Floating_Point_Add_altbarrel_shift_35e" entity appear which make the confuse with the " distance".

    Thnaks anyway...
