Western Digital is identified in the provided evidence as the developer of Whisper, a RISC-V instruction set simulator that can be used in co-simulation environments.

Overview

Western Digital is cited in technical literature as the developer of Whisper, an instruction set simulator. In the referenced MICRO-54 paper, Whisper is described as an instruction set simulator developed by Western Digital and usable in a co-simulation environment.

Whisper

The available evidence characterizes Whisper as a RISC-V-related instruction set simulator with the following stated properties in the cited comparison:

  • It was developed by Western Digital.
  • It can be used in a co-simulation environment.
  • In the cited paper's comparison with Open-Cosim, Whisper is described as supporting only RV32, not handling interrupts, and lacking checkpoint support.

Technical context

The cited source discusses Whisper in the context of processor verification and co-simulation tools for RISC-V processors. The mention appears in a comparison of related co-simulation approaches and verification resources.
