Specification Status

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 (). 

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.

Status Key

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. They are as follows:

* Plan Milestone next Steps:

1. start
2. review by chairs
3. complete (nothing else to do)

** Freeze Milestone next step:

1. start
2. spec development - stable
3. AR approval (ISA/SW AR)
4. acceptance criteria complete (including waivers, ar approval)
5. committee chair approval
6. freeze
7. complete (nothing else to do)

*** Ratification Milestone next step (don't start until freeze is complete):

1. start
2. send out for public review
3. public review complete
4. acceptance criteria complete 
5. committee chair approval
6. TSC approval
7. BOD approval
8. ratified
9. complete (nothing else to do)

**** Specification State values:

1. New
2. Plan Complete
3. Stable
4. Frozen
5. Public Review Started
6. Public Review Complete
7. TSC Approved
8. Ratified
