RISC-V International
NOTE: We have migrated our specification development tracking to Jira. The new All Specifications Under Development replaces the old table-based, static page. Please see the "Historical Status" section for legacy information.
These links provide more information about specifications currently under development:
Any questions or problems should be sent to help@riscv.org or reported at help.riscv.org (GH issue repo which requires authorization and authentication).
The historical specification status, including the information know as the "Specification Dashboard" has been moved to the "Specification Status - Historical" page. Please reference it for legacy information.
The RISC-V specification process is governed by the Ratification Policy and more concisely articulated in the Specification Lifecycle and Milestone Definitions presentation.
This page serves as the starting point for understanding the status of specifications currently being developed by RISC-V. This status is best represented as progress toward the key Specification Milestones (Plan, Freeze, and Ratification-ready) which are obtained sequentially. Specific status for the relevant status columns is detailed in the Status Key section below.
In-process specifications are grouped below into two tables based on whether they impact the RISC-V ISA (In-process ISA Specifications) or not (In-process Non-ISA Specifications). Items should have links to their respective specification repo (), Ratification Plan() if not a Fast-track item, and an Acceptance Criteria Status checklist (). Completed specifications are tracked at the bottom of the page.
This dashboard does NOT intend to showed details status (that's available in the status checklist for the specification, ), but rather the general status in the journey to ratification.
NOTE: This page is maintained by the RISC-V TPMs. To get updates to this page or for questions, contact help@riscv.org.
