HW IP features

  • Flexible data width capability (32/64-bit) on output AXI4-memory map Slave, (32/64/
    128/256/512-bit) on output AXI4-memory map Master interface
  • Flexible data width capability from 8-bit to 1,024-bit in multiples of eight output
  • AXI4-stream Master/Slave interface
  • Interrupt support for indicating completion for traffic generation.
  • Error interrupt pin indicating error occurred during core operation. Error registers can
    be read to understand the error occurred.

Test Procedure

Refer below path for testing different examples for each feature of the IP.
https://github.com/Xilinx/embeddedsw/tree/master/XilinxProcessorIPLib/drivers/trafgen/examples
xtrafgen_interrupt_example.c : This example programs known data to master RAM and command to command ram and param ram. The data will
be taken from master RAM and programmed to the slave in interrupt mode.
xtrafgen_polling_example.c :
his example programs known data to master RAM and command to command ram and param ram. The data will
be taken from master RAM and programmed to the slave.
xtrafgen_static_mode_example.c : This example demonstrates how to use axi traffic generator in static mode.
xtrafgen_master_streaming_example.c : This example demonstrates how to use axi traffic generator in streaming mode.
