Many factors contribute to the bandwidth and latency of the HBM solution, all of which must be considered when designing a system. The Non-Synthesizable Traffic Generator is used to model the traffic masters and allows for quick modifications to the traffic profiles in the axi_tg.txt file. You can set up one traffic generator per AXI port, multiple traffic generators targeting a single port, or multiple traffic generators targeting multiple ports using the Global Addressing option. The solution offers functionality and flexibility beyond that of the example design axi_tg.txt file, which is an example of a simple Write and Read access pattern.

The following section outlines the options for the command input fields and how these should be used. It also highlights the types of usage that might affect the application logic and result in low performance.
