TEJAS: Thermal-Enhanced Joint Architecture Simulator

TEJAS is a high-fidelity, Transaction-Level Modeling (TLM) based simulator for Optical Networks-on-Chip (ONoCs). It provides a comprehensive environment for evaluating Routing and Wavelength Assignment (RWA) algorithms by jointly simulating optical physics, thermal dynamics, and power consumption in 2D and 3D mesh topologies.

Features

• Joint Simulation: Integrated modeling of optical loss, crosstalk, thermal hotspots, and power consumption.
• Modular Architecture: Router microarchitecture decomposed into Circuit, Optical, Thermal, and WDM units.
• Advanced Physics: Detailed models for MRR thermal tuning, SOA gain/noise, and temperature-dependent leakage.
• Scalable Topologies: Support for configurable 2D and 3D mesh networks.
• SMART-RWA: Includes the Staged Multi-objective Adaptive Routing Technique for runtime optimization.
• Comprehensive Metrics: Reports OSNR, BER, Crosstalk, Latency, and Energy per packet.

Requirements

• OS: Linux (Ubuntu/Debian recommended)
• Compiler: GCC/G++ (C++14 or higher)
• SystemC: Version 2.3.3 (included or installed locally)
• Build System: Make

How to Setup and Run

1. Clone the repository:

   git clone https://github.com/vamsikunal/OptiNoc-Sim.git
   cd OptiNoc-Sim

2. Build the simulator:

   cd bin
   make

3. Run a simulation:

   ./optinoc ../config_examples/default.ini

   Results will be generated in the output/ directory.
