Siemens Innovator3D IC is enterprise electronic-design-automation (EDA) software for planning and developing 2.5D and 3D integrated circuits built from multiple dies, including chiplets. Siemens describes it as a unified cockpit for exploring designs and analyzing power, signal, thermal, and mechanical behavior before detailed implementation. It is a specialized semiconductor-design platform, not a general-purpose app; the launch announcement was published on June 24, 2024.
What Innovator3D IC is designed to do
Advanced packages bring multiple dies, interconnects, and packaging structures together. Choices made about their placement and connections can affect electrical behavior, heat, and mechanical stress. Innovator3D IC is intended to let engineering teams plan and assess those interactions as part of a broader design workflow.
Siemens describes the software as spanning design planning, prototyping, predictive analysis, implementation, mechanical design, test, signoff, and release to manufacturing. Its launch announcement says the cockpit unifies power, signal, thermal, and mechanical-stress analysis and supports early “what-if” exploration. These are Siemens’ descriptions of the product and intended workflow; the cited materials do not provide independent benchmarks showing that the approach is faster or less costly.
What is included in the Siemens suite
Siemens’ current product-suite page names four components. Their stated roles are:
#1 Best Overall
| Product | Stated role |
|---|---|
| Innovator3D IC Integrator | Planning, prototyping, and predictive multiphysics analysis for chiplets, interposers, and packages. |
| Innovator3D IC Layout | A named part of the suite; the product-suite page cited here does not provide a more specific description. |
| Innovator3D IC Protocol Analyzer | Standards-based interconnect compliance analysis and vendor-model IBIS-AMI simulation for UCIe links. |
| Innovator3D IC Data Management | A named part of the suite; the product-suite page cited here does not provide a more specific description. |
Siemens also describes an open architecture that can accommodate third-party point solutions. Its materials identify support for 3Dblox and die-to-die interface IP. These claims indicate intended interoperability, not a guarantee that a particular format, tool version, or existing design flow will work without adaptation. Confirm compatibility with Siemens for the specific tools and files your team uses. Siemens Innovator3D IC product-suite information and its 2024 explainer on 3D IC design provide the vendor’s product context.
How it fits into chiplet and 3D IC design
The intended benefit is to evaluate package-level decisions while the design is still being explored, rather than treating electrical, thermal, and mechanical concerns as disconnected tasks. A team can use planning and prototyping to explore a multi-die arrangement, analyze interactions Siemens supports, and carry the design through implementation and later verification and manufacturing handoff.
Rank #2
That makes the platform relevant to organizations working on heterogeneous integration and advanced packaging, where a package may combine different dies and interconnect approaches. Siemens’ April 14, 2026 article presents multiphysics as an early design concern and describes a workflow combining Innovator3D IC Integrator with Calibre analysis tools. This is Siemens’ current positioning; it is not independent validation of design outcomes. Siemens’ 2026 discussion of multiphysics analysis gives the company’s rationale.
Does Innovator3D IC support 3Dblox and UCIe?
Siemens materials identify 3Dblox support and describe Protocol Analyzer as supporting standards-based interconnect compliance analysis and vendor-model IBIS-AMI simulation for UCIe links. The company’s product information also points to die-to-die interface IP support. Those descriptions are useful starting points for an evaluation, but they do not establish compatibility with every implementation, model, or tool in a customer’s flow.
Siemens has published customer testimonials on its 3D IC design solutions page. ASE’s Dr. CP Hung says Innovator3D IC can read and write 3Dblox; Amkor’s JaeBeom Shim describes using Innovator3D IC and Calibre in package-interconnection verification and DFM. These are vendor-published customer statements, not independent performance studies. Siemens 3D IC design solutions and customer statements.
How many pins does Innovator3D IC support?
Siemens’ figures differ across its materials, and the available sources do not explain whether they refer to different releases, configurations, or scopes. They should not be read as a verified capacity increase or as directly comparable benchmarks.

Siemens is not the only vendor with a multi-die design offer. A European Commission decision identifies integrated multi-die chip-design offerings from Siemens and Cadence, including thermal and electromagnetic analysis. That establishes a relevant alternative, but it does not provide a current, like-for-like performance comparison between products. European Commission decision M.10391.

For an evaluation, compare the tools against the engineering work your team actually needs to perform:
- Architecture and package scope: Check support for your chiplet, interposer, and package arrangements.
- Analysis coverage: Verify which electrical, thermal, mechanical, and other analyses are included and how they fit your process.
- Standards and interoperability: Confirm the formats, standards, models, and third-party tools your existing flow requires, including relevant 3Dblox or UCIe use cases.
- Scale: Ask vendors to explain capacity claims in the context of your intended configuration and design.
- Workflow coverage: Determine how planning and implementation connect to verification, test, signoff, and manufacturing handoff.
Siemens’ materials describe capabilities in several of these areas, but vendor descriptions alone do not show that Innovator3D IC is faster or better than a competing tool. A meaningful comparison depends on your designs, integrations, and evaluation criteria.
