The first major releases under the unified Mentor Graphics umbrella focused on structural stability and cross-probing between PADS Logic (schematic) and PADS Layout.
, with "Professional" being a powerful hybrid based on the high-end Xpedition technology.
The Evolution of PADS: A Complete Version History For over three decades, PADS (originally developed by CADAM, later acquired by Mentor Graphics, and now part of Siemens EDA) has been a cornerstone of the printed circuit board (PCB) design industry. Known for its balance of power and usability, PADS evolved from a desktop tool into a enterprise-ready design ecosystem.
Implemented 3D visualization capabilities. It added physical design reuse features and enhanced thermal pad management. mentor graphics pads version history
Developed by PADS Software, Inc. It became a staple for desktop PCB design. In 2000, it was briefly sold to Innoveda before Mentor Graphics acquired Innoveda in 2001 .

PADS (Personal Automated Design System) is a widely-used PCB design software suite that has evolved over four decades through multiple corporate ownerships. Originally a DOS-based tool, it is now part of the Siemens EDA portfolio. The first major releases under the unified Mentor
Recently, the PADS ecosystem has entered a state of flux, with major implications for Standard and Standard Plus users.
The software is currently split into two main "flows": (the "classic" logic/layout environment) and PADS Professional (based on high-end Xpedition technology). 🕒 Notable Version Milestones 1985: First release on DOS for $495.
The history of PADS PCB design software spans over four decades, evolving from a DOS-based tool into a sophisticated suite now under the Siemens EDA PCB Libraries Origins and Early Years (1980s–1990s) Known for its balance of power and usability,
Around 2007, Mentor Graphics rebranded the suite, dropping the "Power" prefix to simplify the product identity and align it with other Mentor flows. The tool became known simply as , PADS Layout , and PADS Router .
Developed as a lower-cost alternative to enterprise-level software, PADS quickly became a staple for independent engineers.
The latest generation of PADS leverages cloud technology to support modern, distributed engineering teams.
