Silvaco Group, Inc, Wiki

Silvaco Group, Inc. develops and sells semiconductor TCAD (technology computer-aided design), EDA (electronic design automation) tools, and semiconductor design IP. Founded in 1984 and headquartered in Santa Clara, California, the company serves foundries, IDMs, fabless design houses, equipment makers, and universities worldwide. Silvaco’s hallmark is connecting physics-based process/device simulation to circuit and library design, positioning the firm as a bridge between fabs and designers.

Product & Platform Overview

1) TCAD Suite

Silvaco’s TCAD helps engineers virtually explore process flows and device architectures before silicon, reducing risk and accelerating ramp:

Victory Process: 3D process simulation (implant, diffusion, deposition, etch, CMP, stress).
Victory Device: Device simulation for CMOS, power devices (Si/SiC/GaN), image sensors, display TFTs, optoelectronics.
Victory Mesh/Visual: Meshing, visualization, and analysis.
Utmost/Utmost IV: Device characterization and SPICE model extraction.
DoE/Analytics: Design-of-experiments, calibration, and sensitivity studies to link fab knobs to device targets.

2) Custom IC Design & Verification

A full custom-analog flow aimed at tighter correlation from schematic to post-layout signoff:

Gateway (schematic capture) and SmartSpice/SmartSpice RF (simulation).
Expert (layout), Guardian (DRC/LVS), Hipex and CLEVER (parasitic extraction, 3D field-solver-based where needed).
SmartView (waveform viewing) and Jivaro-style netlist reduction (from acquired technology) for faster verification.
Power & variability analysis features from prior acquisitions extend coverage for signoff-quality checks.

3) Standard-Cell Library & Characterization

Silvaco’s library automation shortens time to market for foundation IP:

Cello/Viola: Automated standard-cell creation and characterization pipelines.
LibertyForge / CellForge: .lib generation/validation, including 3D-aware and advanced-node options.
These tools target FinFET and GAA nodes and help close gaps between characterization, STA, and silicon.

4) Semiconductor IP (SIP)

Silvaco licenses a broad catalog of design IP used in SoCs and MCUs:

Foundation IP: Standard-cell libraries, SRAMs, ROMs, specialty memories.
Interface & peripheral IP: AMBA subsystems, I3C/I2C/SPI/Quad-SPI/Octal-SPI, GPIO, UART, USB, Ethernet MACs, ADC/DAC, sensor interfaces.
Automotive & industrial: CAN/CAN-FD, FlexRay, LIN, time-sensitive networking, safety-ready components.
The portfolio targets low-power and mixed-signal use cases and is supported by enterprise IP lifecycle management.

5) Computational Lithography

Silvaco offers model-based OPC/RET and proximity correction for advanced optical stacks, aiming to reduce mask turnaround while maintaining pattern fidelity. Integration with its TCAD/EDA environment enables cross-domain studies (mask ↔ device ↔ circuit).

6) Digital Twin & FTCO™

A unifying theme is Fab-Technology Co-Optimization (FTCO): data-driven models that correlate fab parameters to device/circuit behavior. By combining TCAD physics with machine-learning surrogates and silicon feedback, Silvaco promotes “correct-by-construction” design choices and faster yield learning.

Key Application Domains

Power electronics: Si, SiC, and GaN devices (HEMTs, superjunction MOSFETs), converter ICs, and drivers.
Automotive: Safety-oriented libraries and IP, power devices, display and sensor pipelines, and EMI/ESD-aware flows.
Displays & image sensors: TFT/LTPS/LTPO/Oxide modeling, pixel circuits, sensor pixel/device-circuit co-design.
Memory & logic: Device architecture exploration (FinFET, nanosheet, forksheet, CFET concepts), PDK development, and library bring-up.
Photonics & optoelectronics: Device physics and mixed-signal integration for optical links and sensors.
Academia & consortia: Teaching, research, and early exploration of novel materials and structures.

Differentiation

TCAD-to-Signoff Continuum: Few vendors span process/device physics through custom IC implementation, signoff, and IP under one roof; this enables tighter correlation and early detection of manufacturability pitfalls.
Digital-Twin Mindset: FTCO marries lab/fab data with simulation, allowing sensitivity analyses that surface high-leverage process and design knobs.
Library Productivity: Cello/Viola and Forge tools automate repetitive, error-prone library tasks and make 2D/3D transitions more systematic.
Breadth of SIP: Foundation and interface IP reduce SoC integration risk and align with the company’s analog/mixed-signal strengths.

Ecosystem & Workflow Integration

Foundries/IDMs: PDK enablement, device modeling, OPC/RET, and ramp-to-yield support.
Fabless & systems: Analog/mixed-signal design, library/IP bring-up, and variability-aware signoff.
Equipment/materials: Process window exploration and DOE via TCAD.
Universities: Teaching licenses and research collaborations that seed next-gen device concepts.

Business Model & Services

Silvaco licenses software via subscription/term and perpetual models (by product or bundle), licenses SIP under standard commercial terms, and delivers training, modeling, and consulting services (e.g., SPICE model creation, process/device calibration, custom library builds).

Competitive Landscape

TCAD: Competes primarily with other physics-based platforms; differentiation centers on breadth (process + device) and calibration workflows.
Custom IC & signoff: Overlaps with larger EDA incumbents; Silvaco focuses on analog/mixed-signal depth, extraction accuracy, and cost-effective deployment.
Libraries/IP: Competes with specialty IP vendors and internal teams; strength lies in automation and catalog breadth.

Typical Use-Case Threads

New node/device → TCAD DOE and calibration → compact model extraction with Utmost → circuit bring-up in SmartSpice → library characterization in Viola → silicon correlation.
Power platform → SiC/GaN device design in Victory → compact modeling → driver and control IC in custom flow → parasitic extraction and reliability analysis.
Display pipeline → TFT device modeling → pixel circuit co-simulation → layout/extraction → yield analysis and OPC adjustments.
IP-centric SoC → Foundation libraries + memory compilers → interface IP integration → AMS verification and signoff.

Culture & Community

Silvaco runs global SURGE user events, publishes app notes and example decks, and collaborates with customers on methodology. The culture emphasizes pragmatic physics, repeatable automation, and closing the loop between fab reality and design intent.
