Overview

ZeBu is identified in the provided evidence as an emulation target within a RISC-V processor verification methodology. The cited flow emphasizes test portability across multiple execution environments, including simulation, emulation (ZeBu®), FPGA prototyping, and silicon. [C1]

Role in RISC-V verification flows

In the described methodology, tests created during RTL bring-up can continue to be used through later validation stages and even on silicon. ZeBu appears in this context as the emulation stage of that portable validation path. [C1]

The same source describes a broader hybrid RISC-V verification approach that combines constrained-random stimulus and directed test suites to accelerate coverage closure, improve debug efficiency, and support reproducible regression cycles. Within that flow, portability across platforms such as ZeBu is presented as part of a shift-left verification strategy. [C1]

Supported portability context

The evidence states that portable tests can run across:

• simulation,
• emulation, identified specifically as ZeBu®,
• FPGA prototyping, identified as HAPS®,
• and silicon. [C1]

This portability is described as enabling tests developed early in RTL bring-up to retain value throughout later validation phases. [C1]
