What 6SigmaET does
6SigmaET is a London, United Kingdom-based developer of thermal simulation software for the electronics industry, founded in 2009. Its core technology is an AI-enabled multiphysics thermal analysis platform that performs electrothermal co-simulation combining finite element analysis (FEA) and computational fluid dynamics (CFD), alongside electronics cooling simulation, power delivery network design (PTI), and DC analysis (PowerDC) for IC package and PCB signoff. The platform also extends to 3D-IC thermal-aware multiphysics analysis via the Celsius Versa capability. The technology is now positioned within Cadence Design Systems' Celsius Studio Platform and integrates with Cadence's IC, custom IC, microwave/RF, and PCB implementation tools (Virtuoso, Innovus, AWR Microwave Office, Allegro, Integrity 3D-IC).
The product architecture is built around a massively parallelized execution engine that the company claims delivers a 10X performance speedup over prior generations, with AI-enabled optimization features including Monte Carlo analysis, sensitivity studies, metamodel generation, and generative AI-driven design exploration. The solver portfolio addresses electronic systems thermal challenges from chip to enclosure, with explicit positioning for 3D-IC and advanced packaging workloads.
The business model is enterprise B2B electronic design automation (EDA) software, sold through direct sales with field sales teams covering large strategic accounts and inside sales covering mid-market customers. Pricing is quote-based and not publicly disclosed; free trials are offered for evaluation, and a free academic licensing program targets student engineering teams. Named customers span automotive (Robert Bosch), semiconductor IP (Arm), and test & measurement (Rohde & Schwarz) at the enterprise level, plus academic users such as Team Bath Racing Electric and Penn Electric Racing.

6SigmaET product offering
Product offeringCore offering
6SigmaET develops thermal simulation software for the electronics industry. Its offering centers on an AI-enabled multiphysics thermal platform combining electrothermal co-simulation, electronics cooling simulation, and thermal stress analysis. The platform enables in-design analysis to detect and mitigate thermal issues early in electronic system design, integrating FEA and CFD solvers with parallel processing for complex IC, package, PCB, and 3D-IC designs.
Product overview
Cadence Celsius Studio is a unified AI multiphysics thermal platform - the industry's first complete AI-enabled thermal platform for electronic systems. The platform converges electrothermal co-simulation, electronics cooling, and thermal stress into a single cohesive offering. It consists of four main sub-products: Celsius Thermal Solver (the complete electrothermal co-simulation solution combining FEA and CFD), Celsius EC Solver (electronics cooling software with parallel processing), Celsius Advanced PTI (power delivery network design efficiency solution), and Celsius PowerDC (DC analysis for IC package and PCB signoff). The platform integrates seamlessly with other Cadence platforms including Clarity 3D Solver, Sigrity X Platform, Spectre Simulation, Innovus Implementation System, Virtuoso Studio, AWR Design Environment, Allegro X, and Integrity 3D-IC Platform.

6SigmaET competitors and assessment
Company assessmentBroad incumbents
- Synopsys: Synopsys is one of the three primary EDA incumbents with digital, analog, and packaging tools that touch electrothermal and power-integrity analysis. It is comparable as a broad EDA competitor rather than a thermal-specialist direct peer.
- Cadence Design Systems: Cadence is both the acquirer of the 6SigmaET technology and the parent platform hosting the Celsius Studio portfolio. It is the dominant EDA flow into which Celsius is integrated, shaping distribution and competitive dynamics for the technology.
- Siemens EDA (Siemens Digital Industries Software): Siemens EDA (formerly Mentor Graphics) is a major EDA incumbent with broader IC, packaging, and PCB flows that include thermal and reliability analysis. It competes indirectly through portfolio breadth rather than a dedicated thermal product.
- Dassault Systèmes SIMULIA: SIMULIA provides Abaqus and other multiphysics simulation tools used across electronics thermal and structural analysis. Comparable as a broad multiphysics incumbent overlapping with Celsius's thermal-stress and structural capabilities.
Others
- Rescale: Rescale is a cloud HPC platform that hosts third-party simulation tools including thermal and CFD solvers. It is comparable as an enabling infrastructure layer rather than a direct product competitor to 6SigmaET's thermal solvers.
Emerging players
- Altair Engineering: Altair provides simulation software (including thermal and electronics cooling) across mechanical and electronic design domains, with growing overlap into multiphysics workflows targeted at electronics and packaging design.
- Keysight Technologies: Keysight's PathWave and EM simulation tools serve electronic system design with adjacent thermal-aware RF and signal-integrity capabilities. It is a partial-overlap emerging competitor in electronics design simulation.
- Hexagon (MSC Software): MSC Software (Hexagon) supplies Adams, Nastran, and related structural/thermal solvers used in mechanical and electronics reliability analysis. It overlaps with Celsius's thermal stress and mechanical analysis modules.
Direct peers
- Ansys: Ansys is the dominant multiphysics simulation vendor (Icepak, Fluent, Mechanical) with deep overlap in electronics cooling and thermal analysis. It is the most direct competitor to 6SigmaET's electrothermal and electronics cooling capabilities.
- COMSOL: COMSOL Multiphysics offers a widely used general-purpose multiphysics simulation platform that competes for the same electronics thermal and electrothermal simulation workflows that Celsius addresses.
