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. To help Task Group Chairs, Vice-chairs, and specification authors navigate this process, the RISC-V Lifecycle Guide has a whole section on "Specification Lifecycle" with an introductory section describing the process and subsections for each milestone that include step-by-step descriptions of the process.
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. The chairs and vice-chairs of Task Groups, specification authors, and Horizontal and ISA Committee chairs and vice-chairs jointly own ensuring their specifications are listed below and reflect accurate status.
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 ().
Status of active votes by TSC and Committee Chairs can be found on the RISC-V Vote Status wiki page.
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 managed by the RISC-V staff with assistance from each specification owner. To get updates to this page or for questions, contact help@riscv.org.

The following steps and associated next sequential steps for the milestones listed in the tables above may be parallelized at times, but are most simply thought of as a sequential set. All previous steps are done. For more details on each step, see the RISC-V Lifecycle Guide section on "Specification Lifecycle" and it's specific subsections for each milestone, including step-by-step descriptions.
The usable Milestone next Steps are as follows:
* Plan Milestone next Steps:
** Freeze Milestone next step:
*** Ratification Milestone next step (don't start until freeze is complete):
++ ISA AR State (owner)
NOTE: Some Milestone next steps may be marked as "N/A" for "Not Applicable" with an explanation after a trailing "-". For example, "N/A - Grandfathered" means that the step was skipped due to the fact that the process changed after the step would have been completed and it has been "Grandfathered" in (meaning accepted as N/A) as acceptable.
