VHDL AXI4 Slave BFM Test Program
The following code example contains a simple AXI4 slave test program that shows the slave
BFM API being used to communicate with a master and create stimulus. This test program is
discussed further in the
VHDL Tutorials chapter.

-- This is a simple example of an AXI Slave to demonstrate the
mgc_axi4_slave BFM usage.
--
-- This is a fairly generic slave which handles almost all write and read
transaction
-- scenarios from master. It handles write data with address as well as
data after address
-- both. It handles outstanding read and write transactions.
--
-- This slave code is divided in two parts, one which user might need to
edit to change slave
-- mode (Transaction/burst or Phase level) and memory handling.
-- Out of the code which is grouped as user do not need to edit, could be
edited for achieving
-- required phase valid/ready delays.
