RVA22 Profile

Overview

RVA22 is referenced as one of the newer RISC-V profiles supported by a verification flow for RISC-V processor designs. The provided evidence does not define the architectural requirements of the RVA22 profile, but it explicitly lists RVA22 alongside RVA23 as a profile supported by the described verification methodology.

Verification relevance

The evidence places RVA22 in the context of RISC-V processor verification. The described flow combines constrained-random stimulus from STING with directed suites such as ImperasTS to support coverage closure and compliance-oriented validation. The same source states that this flow supports new RISC-V profiles, including RVA22 and RVA23.

Lifecycle and portability context

The verification methodology associated with RVA22 support is described as portable across simulation, emulation, FPGA prototyping, and silicon. The source also characterizes this portability as enabling a “shift-left” methodology, where tests developed during RTL bring-up remain useful through later validation stages and silicon.

Evidence limits

The provided evidence supports only the following limited claims about RVA22:

• RVA22 is a RISC-V profile.
• RVA22 is listed with RVA23 as a newer profile supported by the described RISC-V verification flow.
• The relevant flow includes constrained-random and directed testing, coverage closure, debug support, and portability across multiple execution platforms.

No additional architectural details, mandatory extensions, privilege requirements, or compliance criteria for RVA22 are stated in the provided evidence.
