Sitar V2.0

Sitar is a framework for modeling and parallel simulation of synchronous discrete-event systems.
It consists of a custom modeling language and a lightweight, C++ based simulation kernel.

Here's an example of a behavioral description in Sitar, the corresponding control flow and the simulation output:

Getting Started

Prerequisites

• Linux (tested on Ubuntu 18/20/22)
• Python3
• SCons
• gcc (version >=4.5)
• OpenMP

Installation

1. Download or clone this repository, enter the repository and run the installation script by typing ./install.py in your terminal. This should generate an executable called sitar_translator inside the translator/parser folder.

2. Add the following lines to your ~/.bashrc file to use the sitar commands outside the installation folder. Replace <path> with absolute path of the installation folder.

   export LD_LIBRARY_PATH=<path-to-sitar>/translator/antlr3Cruntime/build/lib:${LD_LIBRARY_PATH}
   export PATH=<path-to-sitar>/scripts:${PATH}
   

Usage

• Refer to /examples/README for running examples.
• Type sitar -h at the terminal for command options.
• (Optional) for enabling syntax highlighting inside Vim editor for sitar language, refer to vim/README\
