SystemVerilog AXI4 Master BFM Test Program

The following code example contains a simple AXI4 master test program that shows the master

BFM API being used to communicate with a slave and create stimulus. This test program is

discussed further in the SystemVerilog Tutorials chapter.

This is a simple example of an AXI4 master to demonstrate the

mgc_axi4_master BFM usage.

This master performs a directed test, initiating 4 sequential writes,

followed by 4 sequential reads. It then verifies that the data read out

matches the data written.

For the sake of simplicity, only one data cycle is used (default AXI4

burst length encoding 0).

It then initiates two write data bursts followed by two read data

bursts.

It then initiates 4 outstanding writes, followed by 4 reads. It then

verifies that the data read out matches the data written.

import mgc_axi4_pkg::*;

module master_test_program #(int AXI4_ADDRESS_WIDTH = 32, int

AXI4_RDATA_WIDTH = 1024, int AXI4_WDATA_WIDTH = 1024, int AXI4_ID_WIDTH =

18, int AXI4_USER_WIDTH = 8, int AXI4_REGION_MAP_SIZE = 16)
