Understanding China’s Semiconductor EDA Ecosystem

Stack Semiconductor helps engineers, universities, and semiconductor organizations understand and navigate China’s rapidly evolving Electronic Design Automation (EDA) ecosystem.

Our focus is on the three foundational layers shaping the modern Chinese semiconductor design stack:

  • Full-flow IC Design Platforms
  • Device Physics and Silicon Modeling
  • Verification, Emulation, and AI-Assisted Validation

As global semiconductor development accelerates, understanding the structure of China’s EDA ecosystem has become increasingly important for ASEAN semiconductor ecosystems, universities, IC design teams, and advanced semiconductor research initiatives.



The Three Pillars of China’s EDA Ecosystem

1. The Chinese EDA Ecosystem

China’s semiconductor EDA ecosystem is structured differently from traditional Western EDA models.

Instead of relying on a single dominant platform provider, China has developed multiple specialized EDA companies that focus on different layers of the semiconductor design flow.

This structure allows specialization across:

  • IC implementation and physical design
  • Device modeling and silicon behavior simulation
  • Verification, emulation, and AI-assisted design validation

The modern China EDA stack is increasingly centered around three major ecosystem pillars:

Empyrean Technology

A full-flow semiconductor EDA platform focused on:

  • Digital IC design
  • Analog and mixed-signal design
  • Physical design implementation
  • Manufacturing-aware EDA workflows
  • IC layout and signoff flows

Primarius Technologies

A semiconductor device modeling and simulation company focused on:

  • SPICE simulation
  • FastSPICE simulation
  • Device modeling
  • DTCO (Design Technology Co-Optimization)
  • Silicon behavior prediction
  • Memory and analog modeling

UniVista

A verification and AI-driven semiconductor design company focused on:

  • Functional verification
  • Emulation systems
  • Simulation acceleration
  • AI-assisted EDA workflows
  • System-level chip validation
  • Debug and verification optimization

Together, these companies form the emerging foundation of China’s domestic semiconductor EDA ecosystem.



2. Empyrean EDA Platform and Key Features

Empyrean Technology is one of the most important semiconductor EDA companies in China and is widely viewed as the closest Chinese equivalent to a full-flow IC design platform.

Empyrean focuses on enabling semiconductor companies to move from RTL design toward physical implementation and manufacturing-aware IC development.

Key Capabilities of Empyrean

Digital IC Design Flow

Empyrean supports digital chip implementation workflows including:

  • RTL design integration
  • Logic implementation
  • Timing optimization
  • Physical implementation
  • Signoff preparation

Analog and Mixed-Signal Design

The platform also supports analog and mixed-signal semiconductor development workflows including:

  • Schematic design
  • Analog layout
  • Device-level integration
  • Mixed-signal implementation

Manufacturing-Aware EDA

Empyrean integrates manufacturing-oriented design flows such as:

  • DFM (Design for Manufacturability)
  • Yield-aware optimization
  • Process-aware design flows
  • Mask and manufacturing integration

Advanced Packaging and Manufacturing Integration

Modern semiconductor systems increasingly depend on advanced packaging technologies including:

  • Chiplet integration
  • 2.5D packaging
  • Heterogeneous integration
  • High-density interconnect systems

Empyrean’s manufacturing-aware EDA structure enables closer integration between semiconductor design and advanced packaging ecosystems.




3. How the China EDA Stack Works Together

The Chinese semiconductor EDA ecosystem is increasingly organized into complementary layers:

Design Implementation Layer

Empyrean Technology

Responsible for:

  • IC design flow
  • Physical implementation
  • Analog and digital design workflows

Silicon Physics and Modeling Layer

Primarius Technologies

Responsible for:

  • Device modeling
  • SPICE simulation
  • Silicon behavior prediction
  • DTCO optimization

Verification and Validation Layer

UniVista

Responsible for:

  • Verification
  • Emulation
  • AI-assisted validation
  • System-level testing

This layered structure creates a distributed semiconductor EDA ecosystem rather than a single monolithic platform.



Comparing the Chinese EDA Stack to Global EDA Platforms

The global semiconductor EDA industry has historically been dominated by large integrated platform companies such as Synopsys and Cadence.

These companies combine:

  • Design implementation
  • Verification
  • Simulation
  • Signoff
  • Device modeling
  • IP ecosystems

within a unified software environment.

China’s EDA ecosystem has evolved differently.

Instead of building a single dominant platform immediately, China has developed specialized companies focused on different parts of the semiconductor design stack.


Global EDA Structure

Synopsys

A global semiconductor EDA platform combining:

  • IC implementation
  • Verification
  • SPICE simulation
  • Signoff
  • IP ecosystems
  • AI-assisted design optimization

Cadence

A semiconductor design platform focused on:

  • Digital implementation
  • Analog design
  • Verification
  • Emulation
  • System analysis
  • Packaging integration
