@alfamanager ,

In file "fifo_axi.txt" , please remove the instantiation of entity "fifo_axi", it causes error for recursive instantiation.

@alfamanager ,

I think you are doing something wrong in the FIFO generation process (I don't see some basic FIFO signals in the instantiation).

First Q - did you read the document https://www.xilinx.com/support/documentation/ip_documentation/fifo_generator/v13_2/pg057-fifo-generator.pdf ?

Read carefully chapters 5 and 6. They show you how to use the FIFO in a testbench.
