The test bench shows BFM_BURST_PROCESSOR doing two WRITE bursts and one READ burst to BFM_MEMORY
peripheral through the AXI4 bus.
X-Ref Target - Figure 13
Figure 13: BFM_BURST_PROCESSOR Simulation Waveform
In Figure 13, BFM_BURST_PROCESSOR is performing two WRITE bursts to BFM_MEMORY at address 0x4000000
and then to 0x40000040. Next it performs a READ burst from BFM_MEMORY at address 0x40000040. The
ModelSim console output is:
# ---------------------------------------------------

# Initializing first
16 locations of AXI Slave BFM memory with value
