In the GUI settings of an AXI BFM core, I changed the data bus width to 128 and the ID width to 8. Then, I generated the IP and output products and opened the example design. When examining the files, I can see that the changed data bus and ID widths have not propagated into cdn_axi4_example_test.v testbench that was created.
Is the user expected to modify the testbench of the example design?
The example design provided with the AXI BFM example is fixed and is not currently updated to reflect the user's design. The user will need to modify the testbench manually for a modified example design.
Automation of the example design will be investigated for a future release.
