At the AXI4 bus interface, my_axi_ip is another master that does a continuous single READ and single WRITE to
BFM_MEMORY.
X-Ref Target - Figure 14
Figure 14: my_axi_ip Waveform
In Figure 14, my_axi_ip issues Read commands and BFM_MEMORY responds with read data. In addition,
my_axi_ip issues Write commands with the date and BFM_MEMORY responds WREADY to accept the date from
the master
At the AXI4-Lite bus interface, the BFM_Lite_Processor is the master that performs single-transfer Write and Read
transactions to my_axi_ip.
X-Ref Target - Figure 15
Figure 15: BFM_Lite_Processor Write Waveform
In Figure 15, BFM_Lite_Processor is performing a single Write at address 0x30000000 with data = 0x03020100.
my_axi_ip responds with WREAD/WVALID signals for each of the Write transactions from the master.
