Siemens today announced that it has entered into an agreement to acquire Defacto Technologies, a privately held electronic design automation (EDA) software company focused on automated system-on-chip (SoC) design creation and integration. The acquisition expands Siemens' EDA portfolio with capabilities that help customers manage growing SoC complexity through automated design creation, earlier implementation assessment, and integrated verification. This move is designed to support semiconductor teams in managing the increasing complexity of advanced architectures by automating connectivity, timing constraints, and power intent process flows.
Defacto Technologies' technology complements Siemens' existing EDA solutions by extending end-to-end continuity across the SoC design lifecycle, from early design creation through downstream implementation, verification, and signoff. The combined offering supports advanced design workflows, enabling automation across critical process flows. As semiconductor companies transition from monolithic designs to chiplet-based and highly configurable SoC architectures, the number of IP blocks and interconnections continues to grow rapidly. Defacto Technologies addresses the challenge of time-consuming and error-prone manual SoC assembly processes by automating assembly, design restructuring, and power intent management using a unified, persistent design database.
Strategic Integration
"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."
