Where is FFT v9.1 test bench?

Jump to solution

Hi All,

There are allways mentioned in forums that use FFT IP core testbench in 

demo_tb/
tb_<component_name>.vhd

 

but I have just made a block design with its HDL wrapper but cant find demo_tb directory

and test bench file. 

I am using windows 10 and vivado 2018.2.2.

 

Thanks

Mostafa

finally I found that when you use an IP in a block diagram design,

it  doesnt generate the test bench. But if you follow the following video for IP instantiation then 

you can see the test bench is generated.

Hi Bandi,

 

The problem is that there is no testbench in simulations

even after generating output products.

Its strange but there is not tb_demo directory as well in the project directory.

Mostafa
