CVA6 is a configurable RISC-V processor core that implements a 6-stage pipeline for both application and embedded use cases, with application-class configurations capable of running Linux.
The project addresses the need for an open-source, production-ready RISC-V CPU design that can scale across different deployment scenarios. It achieves this through a highly parameterizable architecture written in SystemVerilog, allowing users to tailor the core to their specific requirements. The 6-stage pipeline design balances performance with complexity, and the tool supports both FPGA implementation and ASIC synthesis paths, making it suitable for prototyping and production silicon.
Developers should choose this tool if they need a mature, open-source RISC-V core with proven Linux boot capability for application-class systems, or a configurable embedded variant for resource-constrained environments. The project suits organizations building custom silicon, FPGA-based systems, or research platforms where control over the processor design is essential. It is particularly valuable for those who need to modify or extend a CPU architecture rather than use a fixed design, and for teams that want to avoid proprietary licensing constraints on processor IP.
The project maintains active development with regular commits across its codebase, indicating ongoing refinement and bug fixes. Documentation is actively maintained, with updates to the user manual and technical specifications appearing regularly. The issue tracker shows consistent engagement with bug reports and feature requests being addressed. Pull requests are reviewed and merged at a steady pace, demonstrating a functioning contribution workflow. The project sustains multiple active branches for different development efforts, suggesting parallel work on features and maintenance.
