PLANO, TX, July 27, 2026 – Siemens is acquiring Defacto Technologies, adding automated SoC design creation, implementation assessment, and verification to its EDA portfolio. The deal strengthens end-to-end continuity from RTL design, at a time when chiplet-based architectures and ballooning IP block counts make manual SoC assembly increasingly slow and error-prone.
Defacto’s platform automates SoC assembly, design restructuring, and power intent management through a persistent design database. The tooling covers connectivity, timing constraints, and power intent process flows from RTL through signoff.
“With Defacto Technologies, we strengthen our ability to help customers automate SoC design creation and establish trusted design flows earlier in the development cycle,” said Ankur Gupta, executive vice president, IC portfolio, Siemens EDA, Siemens Digital Industries Software. “By extending end-to-end continuity across the SoC design lifecycle, we help semiconductor teams manage complexity, improve productivity and make informed design decisions earlier, supporting faster innovation and higher-quality outcomes.”
“Joining Siemens represents an important next step for our organization and our customers,” said Chouki Aktouf, chief executive officer, Defacto Technologies. “This next chapter opens significant opportunities for our customers by combining our deep expertise in SoC design automation with the breadth of Siemens’ EDA portfolio. Together, we aim to help engineering teams simplify complex workflows, improve productivity, and accelerate innovation across the semiconductor and electronics landscape.”
