|
|
* This file demonstrates how to use the xtrafgen driver on the Xilinx AXI
|
|
* Traffic Generator core. The AXI Traffic Generator IP is designed to
|
|
* generate AXI4 traffic which can be used to stress different modules/
|
|
* interconnect connected in the system.
|
|
*
|
|
* This example demonstrates how to use the Static mode in the Axi Traffic
|
|
* Genrator.In Static mode the core continously genrates fixed address and
|
|
* fixed INCR type read and write transfers based on the burst length
|
|
* configured.
