## 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](https://github.com/intel/rohd-vf) 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)](https://github.com/intel/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](https://github.com/intel/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.
