ModelSIM error

I have taken a Xilinx CoreGen's FFT core and i tried to simulate in ModelSIM. After compilation and when i was loading my design i got an error "Failed to find 'glbl' in hierarchical name".

How to clear this error.

Thanks

Re: ModelSIM error

If the core does not already have the glbl module defined in it, then add the glbl.v file to your file list. It is located at <your_lib_install_root>/xilinx/ise/<version>/ISE/verilog/src/glbl.v.

Re: ModelSIM error

I have added the file glbl.v to the project directory but still i am geting the error.


I have added all the verilog libraries into the project library.

what else should i have to add to my project.

Thanks

Re: ModelSIM error

Sudhir,
You have to load glbl as a top level module along with your current top level module. Assuming top is your current top level module try something as below

vsim [options] top glbl
