In the previous article, we introduced Alibaba's T-Head Semiconductor, which promotes the popularization of RISC-V technology with an open-source approach, from Espressif Systems' innovative wireless SoC chips to Allwinner Technology and GigaDevice's breakthroughs in smart application processors and memory fields. Each company has demonstrated the strong potential and practical application of the RISC-V architecture in their respective fields. Today's article will briefly introduce the companies that provide IP cores and architectural design for RISC-V as well as those that offer software, simulation, and tools for RISC-V.
These companies specialize in designing "cores" of RISC-V processors that can be used by other companies in their chip designs. The core is the central part of a processor responsible for executing computing tasks. These companies do not produce physical chips; instead, they provide designs that other companies can purchase to manufacture their own chips.
SiFive is a fabless semiconductor company that provides commercial processor IP and silicon chips based on the RISC-V Instruction Set Architecture (ISA). SiFive's products include cores, System on Chips (SoCs), IP, and development boards. The company is one of the first to produce chips that implement the RISC-V ISA.
As a leader in the RISC-V space, SiFive aims to guide the potential of RISC-V from mid-to-low-end MCUs and IoT markets gradually into high-performance applications such as automotive. SiFive's RISC-V processors have already covered AI, automotive electronics, data centers, mobile computing, and consumer electronics.
SiFive's processor core IP product portfolio, based on the RISC-V instruction set, offers four major series of processor products suitable for various application scenarios:

The company is the first in China to commercialize RISC-V processor licensing, committed to developing high-performance, low-power processors and their related System on Chip (SoC) platforms to serve the rapidly growing embedded system application field.
Nuclei System Technology's semiconductor products are designed for the core of intelligent electronics, telecommunications, and computer processing. The company has developed configurable low-power and high-performance 32/64-bit RISC-V processors and related solutions for AI applications in the IoT field.
The company's founder, Bob Hu, is the creator of China's first open-source RISC-V core – the Hummingbird E203, and also the author of the first Chinese RISC-V book. Nuclei System Technology has a strong focus and significant influence on the development of RISC-V core intellectual property, expanding China's RISC-V market and ecosystem.
These companies provide software tools and simulation platforms that are used for the development and testing of RISC-V-based processor designs. These tools are crucial for chip designers, as they allow testing and optimization of designs before actual chips are manufactured.
Imperas specializes in developing advanced modeling and simulation technologies that cover a variety of popular microprocessor instruction set architectures (ISAs), including Arm, MIPS, Power, and the recent RISC-V. Imperas products are widely used by the world's leading semiconductor and systems companies.
Imperas recently launched a new RISC-V verification product called ImperasDV™, an integrated RISC-V processor verification solution. RISC-V is an open standard instruction set architecture that allows any System on Chip (SoC) developer to design and extend custom processors while maintaining compatibility with a growing ecosystem of supporting tools and software.
Furthermore, Imperas developed a product known as the "Imperas RISC-V Golden Reference Model," which is an "envelope model" covering the entire RISC-V ISA, including privileged modes. It supports the latest extensions such as Crypto (scalar), Bitmanip, Vector, and DSP/SIMD, as well as user-defined custom instructions and extensions.
The Imperas RISC-V Golden Reference Model is an advanced RISC-V processor model provided by Imperas for software development, testing, and verification purposes, particularly in the early stages of processor design and system development.
Imperas' RISC-V Golden Reference Model is a powerful tool that helps engineers and developers to develop and verify software and hardware without the need for actual hardware.
Synopsys is an American company specializing in Electronic Design Automation (EDA), headquartered in Sunnyvale, California, focusing on silicon design and verification, silicon intellectual property, and software security and quality. The company provides tools and services for the semiconductor design and manufacturing industry, including tools for logic synthesis and integrated circuit physical design.
Here are some key RISC-V related products:
