Leadership Transition at Silvaco: Babak Taheri Departs as Walden Rhines Assumes CEO Role

Silvaco Group Inc. (SVCO), a leading provider of TCAD, EDA software, and SIP solutions that drive semiconductor design innovation through AI-powered digital twin modeling, has undergone a significant leadership change. Babak Taheri has departed his position as Chief Executive Officer, with his exit taking effect on August 19, 2025, concluding his nearly seven-year tenure at the helm of the semiconductor software company. The board has named Walden Wally Rhines as his successor, effective immediately.

End of an Era: Babak Taheri’s Seven-Year Leadership Journey

Babak Taheri’s departure marks the end of an extended leadership chapter at Silvaco. Under his direction, the company focused on developing TCAD and EDA solutions that support the semiconductor industry’s evolving design needs. The transition reflects the company’s strategic repositioning as it navigates competitive pressures and technological advancements in the semiconductor software sector. His exit comes as the industry continues to emphasize AI-driven innovation and automation in chip design workflows.

Who Is Walden Rhines? A Veteran with Deep Industry Roots

Walden Wally Rhines brings an impressive pedigree to Silvaco’s top role. He has been serving on Silvaco’s board of directors since September 2022, also holding a seat on the audit committee. Beyond his Silvaco board service, Rhines currently holds the position of President and Chief Executive Officer at Cornami, Inc., a role he has maintained since March 2020. Additionally, he chairs the board of Qorvo, Inc. (QRVO), a major player in semiconductor solutions.

Rhines’ career trajectory spans several decades of semiconductor industry leadership. He previously served as CEO of Mentor Graphics Corporation from 1993 until the company’s acquisition by Siemens in March 2017. Following the acquisition, he remained at Siemens, serving as President and Chief Executive Officer of Siemens EDA—the renamed division that succeeded Mentor Graphics. His tenure at these industry titans has positioned him as a seasoned executive with deep expertise in EDA software, semiconductor design tools, and digital transformation.

Strategic Implications of the Leadership Change

The appointment of Rhines suggests Silvaco’s board views his extensive leadership experience and industry connections as critical assets for the company’s next growth phase. His background navigating major mergers and acquisitions, combined with his ongoing roles across the semiconductor ecosystem, could position Silvaco to accelerate its competitive positioning and expand its market influence in the semiconductor software space. The shift represents both continuity—through his existing board involvement—and renewal through new strategic direction.
