Abstract

The semiconductor industry is undergoing a major transformation driven by open-source Electronic Design Automation (EDA) ecosystems, open Process Design Kits (PDKs), cloud-native ASIC flows, and AI-assisted hardware design methodologies. Historically, Application-Specific Integrated Circuit (ASIC) development required access to expensive proprietary EDA suites from vendors such as Cadence, Synopsys, and Siemens EDA, making custom silicon development inaccessible to startups, SMEs, universities, and independent innovators.

Today, mature open-source EDA frameworks—including Yosys, OpenROAD, OpenLane, Ngspice, Magic, KLayout, and the SkyWater SKY130 PDK—have democratized silicon design and significantly lowered barriers to semiconductor innovation.

This white paper presents:

A comprehensive overview of open-source EDA ecosystems
