The Mentor Graphics PADS version history reflects the software's evolution over several decades, from its early beginnings as a basic PCB design tool to its current status as a comprehensive PCB design platform. Throughout its history, PADS has consistently delivered innovative features, improved performance, and enhanced capabilities, making it a popular choice among electronics designers and manufacturers. As the electronics industry continues to advance, it is likely that PADS will continue to evolve and adapt, providing designers with the tools and capabilities they need to create complex, high-performance designs.

Understanding the version history of PADS provides valuable context for how desktop PCB design tools evolved to meet the demands of high-speed digital design, dense form factors, and cloud-connected collaborative workflows. The Early Eras: DOS to PADS-Perform (1980s–1990s)

This era focused on modernizing the user interface (DxDesigner) and enhancing integration with analysis tools.

In 2015, Mentor Graphics restructured the brand into three distinct tiers based on complexity:

Improved routing, 3D visualization, and design rule checking (DRC). PADS VX.2.10 (2021)

Operating in the DOS environment, early versions focused on basic footprint creation, netlist importing, and manual interactive routing. It gained popularity for its speed and low hardware requirements compared to mainframe CAD tools.

Whether you are dealing with like DDR memory or RF signals?

PADS Professional integrated Mentor’s high-end Xpedition technology, giving desktop users access to the world-class Sketch Router —an auto-assisted routing engine that allowed users to draw a path with a mouse stroke and watch the software automatically route dozens of traces neatly along that path. PADS VX.2 (2016–2020)

In 1997, Mentor Graphics acquired PADS, and the software became an integral part of the company's portfolio of design tools. Under Mentor Graphics, PADS continued to evolve and improve, with a focus on integrating the software with other Mentor Graphics tools and platforms.

Introduced thermal analysis tools and expanded differential pair routing rules, allowing physical constraints to be defined directly from the schematic.

Introduced localized language support (including virtual keyboard entry) and expanded differential pair symmetry checks to combat electromagnetic interference (EMI).

| | Branding | Example Versions | |------------|--------------|-----------------------| | 1986–1994 | PADS‑PCB | v1.0 – v3.5 (DOS) | | 1995–1999 | PowerPCB | PowerPCB v1.0 – v4.0 | | 2000–2007 | PADS (year‑based) | 2000, 2004, 2005, 2007 | | 2009–2015 | PADS 9.x | 9.0, 9.2, 9.3, 9.4, 9.5 | | 2015–2020 | PADS VX | VX.0, VX.1, VX.2 up to VX.2.10 | | 2021–present | PADS Professional (Siemens) | Pro 1.0, 2.0, 3.0, 3.1 |

Version 9.5 added robust 3D visualization capabilities. Designers could view their board layouts with step-model components to check for mechanical clearance issues before manufacturing.

, catering to the growing market of independent engineers and smaller design teams. Throughout the 90s, it solidified its reputation as the "desktop PCB tool of choice," eventually being acquired by Mentor Graphics The Mentor Graphics Era: 2000s – 2016
