+-- This testbench is a Minimum Working Example (MWE) of VUnit's resources to read/write data from a buffer
+-- allocated in a foreign C application, and to verify AXI4-Stream components. Data is sent to an AXI4-Stream
+-- Slave. The AXI4-Stream Slave is expected to be connected to an AXI4-Stream Master either directly or
+-- (preferredly) through a FIFO, thus composing a loopback. Therefore, as data is pushed to the AXI4-Stream
+-- Slave interface, the output is read from the AXI4-Stream Master interface and it is saved back to the buffer
+-- shared with the software application.
