Overview

auto-regression is listed as a built-in feature of TatsuProject/rvgen. The repository is described as a "Pure-Python RISC-V instruction generator" that includes built-in functional coverage, auto-regression, and CI-ready dashboards.

Evidence-supported context

The available evidence places auto-regression in the context of a RISC-V instruction-generation toolchain. Specifically, it appears alongside two other built-in capabilities:

• functional coverage
• CI-ready dashboards

This indicates that, within the evidence provided, auto-regression is presented as part of rvgen's integrated verification or validation support rather than as a separately documented standalone concept.

Scope of available information

The evidence does not provide implementation details, command-line usage, configuration format, regression scheduling behavior, or output semantics for auto-regression. Therefore, no further technical mechanism can be described from the provided sources alone.
