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.
