Golirev-IDE

An online Verilog IDE based on YosysJS using Svg.js to create the svg element. YosysJS is an Emscripten-compiled version of the YosysJS logic synthesis tool. The idea of this project is to display digital schematics and to be able to evaluate them.

Here is a demo of the project : http://johndro.github.io/

Current state of the project

This project is not finished.

What is working / done :

• Parsings the data from the JSON file
• Generating gates on the SVG element

What is not working / not done :

• Component placement (currently the placement is too slow.)

Features :

• Verilog Editor, interactive schematic viewer (zoom, drag and span) and automatic placement using simulated annealing :

• Digital gates :

• Display errors in your Verilog code :

Dependencies :

• YosysJS
  • Synthesises the Verilog code
  • Provides the netlist of the equivalent schematic as an JSON file
• Svg.js
  • A lightweight library for manipulating and animating SVG
• Svg.js plugins
  • svg.draggable.js
    • An extension for the svg.js library to make elements draggable
  • svg.pan-zoom.js/
    • An extension for the svg.js for panning and zooming SVG elements
• CodeMirror
  • A text editor implemented in JavaScript

TODO

• Improve placement performances, currently the placement is very slow and sometimes innacurate.
• Look at wire length placer (built-in yosys)
• Finish to add components (chapter 5 on the yosys manual)
• Use AIG models and Wavedrom in order to evaluate circuits and display results
