PLANO, TX, Jan 14, 2026 – Siemens has acquired ASTER Technologies (“ASTER”) to extend design for test (DFT) capabilities across its electronic design software. The acquisition integrates ASTER’s “shift-left” DFT technology into Siemens’ Xpedition and Valor software within the Siemens Xcelerator portfolio. The integration links PCB design engineering with manufacturing through a digital thread, enabling earlier defect detection, reduced costs, faster development cycles, and improved product quality and reliability.
Addressing Growing Complexity in Electronics
The acquisition comes at a time when automotive electronics demand and 5G integration in electronic systems are driving the need for testing strategies. Embedded DFT in PCB design helps teams detect defects and reduce re-spins, returns, and field failures. Companies want integrated PCB design and test workflows to meet compliance requirements.
ASTER’s Expertise Enhances Siemens’ Design for Manufacturing (DFM) Offering
ASTER builds software for PCB verification, assembly, and test. Its portfolio includes DFM design verification, test coverage analysis, and test programming for fabrication and assembly workflows. The TestWay product enables DFT planning and execution during PCB design and manufacturing preparation. Combined with Siemens’ Valor design for fabrication and assembly tools, TestWay supports an integrated DFM approach.
“The addition of ASTER Technologies is a game-changer for our customers in the PCB design and manufacturing space. By integrating ASTER’s market-leading test engineering software, we are empowering our customers to optimize designs much earlier in the design cycle,” said AJ Incorvaia, senior vice president and general manager, electronic board systems at Siemens Digital Industries Software. “This can dramatically reduce costs, accelerate time-to-market and helps to ensure the highest levels of product quality and reliability. It’s about giving our customers a complete, integrated solution that sets them up for success from the very first design concept through final production.”
Strategic Fit for Complex Electronic Systems
Used across computing, HPC, automotive, and networking designs, ASTER’s tools support development of PCB test strategies. The acquisition strengthens Siemens’ DFM offering for the global PCB market.
“Joining forces with Siemens is an incredibly exciting next chapter for our team and our customers. We’ve always been passionate about helping engineers create flawless PCB designs through advanced test coverage analysis,” said Christophe Lotz, founder and chief executive officer, ASTER Technologies. “Now, as part of Siemens, we have an unparalleled opportunity to integrate our expertise into a broader, industry-leading portfolio. This means our innovative solutions can reach more customers, enabling them to achieve even greater efficiency, quality and competitive advantage. We are thrilled to contribute to Siemens’ vision of a truly integrated digital thread for electronics design and manufacturing with just enough test.”
Expanding Siemens’ EDA Portfolio
The acquisition embeds manufacturing and test capabilities into Siemens’ PCBA design portfolio. Integrating ASTER’s technology into the Siemens Xcelerator portfolio expands DFM coverage. The change allows teams to address manufacturing requirements and plan test strategies during the development stage.
