Mentor Graphics Pads Version History ((full)) -

After a brief pause, Mentor Graphics "resurrected" the PADS name in 2003 for the low-to-mid range PCB market. The following decade became a period of extraordinary development, marked by the release of several now-legendary versions.

This release was a major milestone focusing on user productivity. According to InnoFour and Siemens, key enhancements included:

This was a major update that introduced unique technology for DFM (Design for Manufacturing) and interactive routing, as highlighted by Jim Martens in his blog post 1.2.5. It also introduced a new installation method 1.2.4 .

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 .

arrived in 1993 as a significant transitional milestone. It was the first version to offer dual compatibility, operating in both DOS and the emerging Windows operating systems. This move foreshadowed the industry's inevitable shift toward graphical user interfaces (GUIs) and away from command-line-based systems, bridging the gap between the old and new computing standards.

Following a brief period of iterative "PADS 2005" and "PADS 2007" releases, Mentor Graphics unified the platform architecture under the PADS 9.0 roadmap. This generation focused heavily on signal integrity and scalable design rules. This is a high-level overview — for detailed

A DOS-based layout tool that gained immense popularity among engineering firms due to its low hardware requirements and efficient keyboard-driven command structure.

PADS 9.5 was one of the most stable and longest-running versions in the software's history. It added native support for virtual prototyping, extended differential pair constraints, and refined the automated test point generation. Many legacy engineering environments remained on PADS 9.5 for years due to its rock-solid reliability.

Versions of PADS generally fall into three distinct eras of numbering and architecture: History of PADS - PCB Libraries Forum
