Overview

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 Generator.In Static mode the core continuously generates fixed address and fixed INCR type read and write transfers based on the burst length configured.

1.01a adk  03/09/13 First release
2.00a adk  16/09/13 Fixed CR:737291
4.1   ms   01/23/17 Modified xil_printf statement in main function to
                    ensure that "Successfully ran" and "Failed" strings
                    are available in all examples. This is a fix for
                    CR-965028.
      ms   04/05/17 Added tabspace for return statements in functions for
                    proper documentation while generating doxygen.
4.9  vlt  12/18/25 Update Doxygen comments to include SDT flow details.
     vlt  01/27/26 Fixed codespell issues.

Returns

XST_SUCCESS if tests pass

XST_FAILURE if fails.

Note: None.

int XTrafGenStaticModeExample	(	XTrafGen *	InstancePtr,
		UINTPTR	BaseAddress
	)

This function demonstrates the usage Traffic Generator It does the following:

  - Set up the output terminal if UART16550 is in the hardware build
  - Initialize the AXI Traffic Generator device
  - Fill's the Target memory with required data
  - Enable the Traffic generation
  - Disable the Traffic generation
  - Return test status and exit

Parameters

InstancePtr	is a pointer to the instance of the XTrafGen component.
DeviceId	is Device ID of the Axi Traffic Generator Device,
InstancePtr	is a pointer to the instance of the XTrafGen component.
BaseAddress	contains the base address of the device

Returns: -XST_SUCCESS to indicate success -XST_FAILURE to indicate failure

Note: In XSCT/classic flow, DeviceId is used to look up the device configuration.
