About ROHD #

  • Full power of the modern Dart language for hardware design and verification
  • Makes validation collateral simpler to develop and debug. The ROHD Verification Framework helps build well-structured testbenches.
  • Develop layers of abstraction within a hardware design, making it more flexible and powerful
  • Easy IP integration and interfaces; using an IP is as easy as an import. Reduces tedious, redundant, and error prone aspects of integration
  • Simple and fast build, free of complex build systems and EDA vendor tools
  • Can use the excellent pub.dev package manager and all the packages it has to offer
  • Built-in event-based fast simulator with 4-value (0, 1, X, and Z) support and a waveform dumper to .vcd file format
  • Conversion of modules to equivalent, human-readable, structurally similar SystemVerilog for integration or downstream tool consumption
  • Run-time dynamic module port definitions (numbers, names, widths, etc.) and internal module logic, including recursive module contents
  • Leverage the ROHD Hardware Component Library (ROHD-HCL) with reusable and configurable design and verification components.
  • Simple, free, open source tool stack without any headaches from library dependencies, file ordering, elaboration/analysis options, +defines, etc.
  • Excellent, simple, fast unit-testing framework
  • Less verbose than alternatives (fewer lines of code)
  • Enables higher quality development
  • Replaces hacky perl/python scripting for automation with powerful native control of design generation
  • Fewer bugs and lines of code means shorter development schedule
  • Support for cosimulation with verilog modules (via ROHD Cosim) and instantiation of verilog modules in generated SystemVerilog code
  • Use modern IDEs like Visual Studio Code, with excellent static analysis, fast autocomplete, built-in debugger, linting, git integration, extensions, and much more
  • Simulate with various abstraction levels of models from architectural, to functional, to cycle-accurate, to RTL levels in the same language and environment.

ROHD is not a new language, it is not a hardware description language (HDL), and it is not a version of High-Level Synthesis (HLS). ROHD can be classified as a generator framework.

You can think of this project as an attempt to replace SystemVerilog and related build systems as the front-end methodology of choice in the industry.

One of ROHD's goals is to help grow an open-source community around reusable hardware designs and verification components.
