On October 21, Siemens announced that its Fuse EDA AI Agent would extend into electrothermal codesign for advanced 3D integrated circuits (3D ICs). The system is designed to coordinate power, electrical and thermal analysis across nine workflow stages and seven Siemens electronic-design-automation (EDA) tools. Siemens says the automation can reduce setup effort by up to 95%; that is a company-reported figure, not an independently described benchmark in the available announcement details. 11
What the 3D-IC workflow is meant to do
Multichip packages used in AI systems need electrical behavior, power consumption and heat to be considered together. Siemens describes the new capability as combining analyses that were previously separate into an automated workflow, so design constraints can be identified while changes are still possible. 2
An engineer provides design goals, and Fuse coordinates work across EDA tools through Siemens’ Intelligence Center X. The workflow is intended to connect electrical and thermal analysis and flag results that do not meet the specified goals. 2
Siemens says the process spans nine automated stages across seven of its EDA tools. The announcement summary does not identify every stage or map individual tools—including Innovator3D IC, Calibre 3DThermal and Simcenter FloTHERM—to specific tasks. 11
How this extends Siemens’ self-verifying agents
The October announcement builds on Siemens’ earlier work with Nvidia on self-verifying, long-running EDA agents. That approach has Fuse coordinate design tasks and check its decisions against deterministic, physics-based EDA engines. 11

The distinction matters: the agent can plan and orchestrate a workflow, but the claim is not that AI replaces simulation or physical verification. Siemens describes established engineering tools as the basis for checking whether decisions are valid. 8

What the 95% figure means—and what remains unclear
The Siemens announcement describes a reduction of up to 95% in setup effort for the automated workflow. 11 A separate news report characterizes the potential benefit as reduced engineering labor, but the available material does not specify benchmark conditions or establish that the figure applies broadly across designs.
2
The announcement summary also does not provide typical reasoning-step counts, runtimes, or the number of design points explored. Nor does it give a quantified improvement in design coverage. Those details would be needed to compare the workflow directly with a manual process.
The supported takeaway is narrower: Siemens is applying its self-verifying agent approach to 3D-IC electrothermal design, coordinating multiple analyses and tools while relying on EDA engines for engineering checks. The stated setup-effort reduction is promising, but the published summary does not provide enough methodology to assess how it performs across different projects. 8
