The 2025 Free Silicon Conference (FSiC) will take place at IHP Microelectronics (Frankfurt an der Oder) on July 2, 3, 4 2025 (Wednesday to Friday). This event will build on top of the past FSiC editions. The conference will connect experts and enthusiasts who want to build a complete Free and Open Source CAD ecosystem for designing analog and digital integrated circuits. The conference will cover the full spectrum of the design process, from system architecture, to layout and verification.
Submission
Submissions ended on May 1st.
