Trace Monitor

Trace Monitor is our new low-level HW/SW toolset to assist in Network-on-Chip evaluation with adaptive accuracy. 100Mbit/s Ethernet connection is used to transfer monitoring data from any real system in realtime. This data can be further analyzed afterwards.

Transaction Generator 2

Transaction Generator 2 is a SystemC simulator and traffic generator for architecture exploration and benchmarking. It generates traffic according to an abstract application and platform models for network-on-chip (NoC) models. It's designed to support interfacing NoCs described in RTL or higher abstraction levels, such as OCP-IP TLM sockets.

Transaction generator 2 and the related programs and network-on-chip models are released under LGPL licence. In addition to TG, the package includes approximate DRAM model (ADM), ExecutionMonitor for viewing the results, set of test applications for NoC benchmarking, and set of reference NoC implementations.

Snapshots from the TG package will be also published in OCP-IP site because the tool has been adopted by OCP-IP Network-on-chip benchmarking workgroup.

Traffic Generator

Traffic Generator (TG) is an RTL VHDL-based tool for network performance evaluation on FPGA. Multiple Traffic Generators are instantiated on an FPGA chip. TGs communicate through the NoC under benchmarking, emulating the final communication case defined by simple yet powerful models of the system's communication behavior. These communication models can be configured at the run-time without the need of tedious logic synthesis every time.

Traffic generator and the related programs are released under LGPL licence.

Included programs
Traffic Generator VHDL files for simulation and synthesis
TG NoC monitor Additional NoC monitors that give further information of network usage
TG Commander A computer front-end for TG FPGA runtime configuration
Documentation
PDF files for TG and Monitor usage Included in the release package.
System requirements
FPGA development board with RS-232 UART (serial port)
A computer with RS-232 UART
FPGA chip with at least 100k port equivalents (30k LUTs), preferably more

Transaction Generator

Transaction Generator is a SystemC simulator for architecture exploration and benchmarking which composes the application and platform models as well as the mapping information. It can simulate the workload model on any Network-on-Chip model provided it has an OCP TL2 interface.

Transaction generator and the related programs are released under LGPL licence.

Included programs
Transaction Generator SystemC simulator
Dynamic Arex Frontend for Transaction Generator
Execution Monitor Visualization tool for simulation
Tg2execmon Feeds simulation results to Execution Monitor
