In the field of semiconductor technology, compact modeling, and IC designs, the OpenPDK Initiative provides an international platform for discussing advanced technologies, fostering collaboration among industry and academic leaders in electronic design automation (EDA). We review selected R\&D topics presented at a recent event by prominent academic researchers and industrial professionals who presented and discussed innovative approaches in CAD/EDA tools, techniques including compact/SPICE modeling, and IC design that address the demands of emerging semiconductor technology applications. However, the semiconductor industry also faces many challenges in maintaining the growth of its workforce with skilled technicians and engineers. To address the increasing need for well-trained workers worldwide, we must find innovative ways to attract skilled talent and strengthen the local semiconductor workforce ecosystem. The FOSS CAD/EDA tools with the recently available open access PDKs provide a new platform to connect IC design beginners, enthusiasts and experienced mentors to benefit from the collaboration opportunities enabled by the fast-growing open-source IC design movement. The collaborative development of open-source integrated circuit (IC) designs is becoming increasingly feasible due to the rapid expansion of OpenPDKs recently offered by SkyWater, GF and IHP with an open schedule of MPW Runs for FMD-QNC project in 2024-25. This paper demonstrates the FOSS CAD/EDA contribution to the SPICE/Verilog-A modeling/standardization, compete IC design flow (Xschem, Qucs-S, ngspice, Xyce, OpenVAF, OpenEMS, Magic, kLayout, OpenRoad), in addition selected, open-source examples of analog/RF and digital IC designs will be presented.
