Some user applications such as video streaming and Ethernet-based applications make use of I/O ports on the platform to stream data into and out of the platform. For these applications, performing software and hardware emulation of the design requires a mechanism to mimic the hardware behavior of the I/O port, and to simulate data traffic running through the ports. I/O traffic generators let you model traffic through the I/O ports during software and hardware emulation in the Vitis application acceleration development flow, or during logic simulation in the Vivado Design Suite. Hardware emulation supports both AXI4-Stream and AXI4 memory map interface I/O emulation.
Important: Software emulation supports only AXI4-Stream I/O emulation and is not supported on Zynq®-7000 devices.
