In-process Non-ISA Specification Status

In-process Non-ISA Specification Status

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.  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:

1. build plan
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, or 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)

++ ISA AR State (owner)

1. Development (not ready for AR) (TG/IC)
2. Queued (AR)
3. Reviewing (AR)
4. Reworking (if necessary as a result of the review after complete goes back to the queue) (TG/IC)
5. Approved (AR)

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.

**** 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
