Thanks a lot. This works!
It's not so handy as when I use gtp for implementation in ISE, as I
can define only the signals that I am using, and the tool deals with
the rest of them. Now I have to say what happens to each of the
component ports, but I wouldn't call that a problem :-)

Cheers,
Ruzica

Probably the easiest fix is to use direct instantiation.
Where you currently have

  some_instance_name: GTP_DUAL 
                        generic map (whatever)
                        port map (whatever);

you could instead write

  some_instance_name: entity THE_LIB.GTP_DUAL
                        generic map (whatever)
                        port map (whatever);

where THE_LIB is the name of the library into which GTP_DUAL
has already been compiled.  Using direct instantiation
in this way, there is no need for a component declaration.

Yes.  I think I was just being stupid, and looking at my 
WebPack installation which perhaps lacks those components.

Hi Jonathan,

Thanks for your answer. I just saw that the component GTP_DUAL is not
inside the package unisim.vcomponents. Instead it is instantiated as
an entity in another file. How can I tell Modelsim where to search for
this component instantiation?

It should be defined in the folder where ISE has been installed in the
path Xilinx\10.1\ISE\vhdl\src\unisims. You should follow the
guidelines in http://www.xilinx.com/support/answers/24800.htm
in order to install it in Modelsim.

Errrm, it sounds like there's no component declaration :-)

The fact that an entity/architecture exists in a library
does not allow the VHDL compiler to know about it by magic.
You probably forgot a use clause, for the package containing
the gtp_dual component declaration.  And the synthesis tool
(ISE?) probably cheats, and assumes it knows all about the
Xilinx primitives already.

I can't find the gtp_dual component anywhere in my Xilinx
simulation library sources; what am I missing?

  Hello all,

 I am using Modelsim 6.3 and ISE 10.1 and have a gtp_dual in my
design. When I try to simulate it, Modelsim reports the following
error:

 (vcom-1141) Identifier "gtp_dual" does not identify a component
declaration.

I have all the libraries with smartmodels installed in Modelsim, in
fact I can see the component gtp_dual in Unisim and Simprim libraries
in Modelsim workspace. However, it seems that it does not recognize
this option.
Does someone know what could be the problem?
Many thanks.

Ruzica
