Why RapidRTL?

One button does it all. Linting, simulation, project building, and synthesis for any vendor—unified in a single, clean workflow.

One Command

Linting, simulation, synthesis—all from a single Makefile target.

make simulation

Cocotb Ready

Python-based verification out of the box. Write tests in minutes.

pytest-style tests

Any Vendor

Xilinx, Lattice, or Altera—same workflow, same commands.

VENDOR=xilinx | lattice | altera

Smart Linting

Hierarchy-aware VHDL/Verilog linting catches issues before synthesis.

make linting

Built for Modern Hardware Design

RapidRTL abstracts the complexity of vendor tools, giving you a clean, code-first environment for FPGA development.

Multi-Vendor Support

Write once, target anywhere. Unified build flows for Vivado, Radiant, and Quartus without changing your source.

Automated Register Bank

Define registers in YAML. We generate the VHDL packages, C headers, and Python constants automatically.

Smart Simulation

Integrated Cocotb environment. Run Python-based testbenches with GHDL, Verilator, or commercial simulators.

Docker & CI/CD

Pre-built Docker containers for both vendor tools and OSS simulation. Reproducible builds, every time.

Dependency Management

Intelligent handling of IP cores and external VHDL libraries. Auto-cloning and version control.

Advanced Linting

Hierarchy-aware linting for VHDL/Verilog. Catch syntax errors and structural issues before synthesis.
