Overview
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 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.
