OVERVIEW
Packet Generator is a software tool that will be running on a Host computer and generate traffic patterns. AXI Packet Generator is a
product that generates series of AXI4 compliant packets which can be used by emulator platform to generate traffic on DUT’s
interfaces. It can also be used on Simulation platform to generate traffic on simulation environment on DUT’s interface.
FEATURES
The AXI Traffic Generator has following features:
• AXI4 interface is used for register access and data transfers.
• Performs Multi-Mode operation (AXI4 Master, AXI4-Lite
Master, and AXI4-Stream Master).
• Flexible data width capability (32/64-bit) on output AXI4 Slave,
(32/64/128/256/512-bit) on output AXI4 Master interface
• Flexible address width capability from 32 to 64-bit on AXI4
Master Interface
• Flexible data width capability from 8-bit to 1,024-bit in
multiples of eight output AXI4-stream Master/Slave interface
• Supports AXI4-Lite Master interface for system initialization in
processor-less system.
• 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. Only supported in Advanced mode.
• Initialization support through Memory initialization files to
internal RAM (CMDRAM, PARAMRAM, and MSTRAM) allows
you to initialize the contents of all RAMs for a desired traffic
profile.
• External global start/stop to synchronize multiple AXI Traffic
Generators in the system and to enable AXI Traffic Generator
without processor intervention.

BENE FI T S
The AXI Traffic Generator can be used in different
application at Simulation Platform and at Emulation
Platform and following are the benefits:
• Flexible data width capability from 8-bit to 1,024-bit in
multiples of eight output
• 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.
• Two Different Modes can be set for following use-
cases:
Custom Mode
o This mode allows selecting different AXI4 interface
traffic generation.
o The available options are AXI4, AXI4-Stream, and
AXI4-Lite that include these modes
High Level Traffic Mode
o This mode allows generating IP specific traffic on
the AXI interface for pre-defined protocols.
o The currently supported traffic profiles include:
1. Video Mode
2. PCIe Mode
3. Ethernet Mode
4. USB Mode
5. Data Mode
