Mentor Graphics Pads Version History Jun 2026

The version history of PADS, developed by Mentor Graphics Siemens EDA

Mentor Graphics abandoned the year-based naming system in favor of version numbers, launching the PADS 9.x generation. PADS 9.0 represented a major structural overhaul. It integrated DxDesigner as an alternative, enterprise-grade schematic front-end option alongside the classic PADS Logic. This allowed PADS users to utilize Mentor's high-end component library management systems. PADS 9.3 & 9.4 (2011–2012)

Modern updates continue to refine auto-routing and placement heuristics using machine learning principles to optimize dense layout patterns.

Introduced a modern graphical user interface (GUI), dynamic copper pouring, and basic shape-based autorouting.

PADS (Personal Automated Design System) has evolved over more than 30 years from a desktop-focused PCB design tool into a high-end platform integrated into the Siemens EDA ecosystem. Originally created by Gene Marsh, it underwent significant shifts in ownership—moving from Innoveda to in 2001, and eventually to Siemens in 2017.

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.

The history of Mentor Graphics PADS is a history of democratizing PCB design. From its humble DOS origins as a 256-pin tool to today’s AI-assisted, cloud-connected, high-speed layout engine, PADS has survived multiple acquisitions (CAD Software -> PADS Software -> Innoveda -> Mentor Graphics -> Siemens) because it solved the fundamental problem: giving the engineer control without the workstation price tag.

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 .

The software’s journey is marked by key acquisitions that integrated advanced simulation and layout technologies: : Founded by Gene Marsh as PADS Software .

Added an integrated 3D viewer allowing designers to view the physical board assembly and export STEP models to mechanical CAD software like SolidWorks.

: Added features for RF design, such as via matrixing and DXF-in import. It also improved high-speed routing and introduced Design for Fabrication (DFF) analysis. PADS 9.x (approx. 2009–2013) This allowed PADS users to utilize Mentor's high-end

If you are looking to upgrade, understanding the specific improvements in the newer VX.2 releases can help you decide which features will best improve your current design workflow.

Direct integration with the PartQuest portal gave engineers access to millions of pre-made schematic symbols, PCB footprints, and 3D STEP models, drastically reducing library creation time. PADS Professional Premium (2022–Present)

The mid-1990s marked a crucial turning point for the platform when it was rebranded under the iconic name, a moniker many long-time engineers still remember. PowerPCB V1.0 arrived in 1995 for Windows 95. PowerPCB V2.0 for Windows NT followed in 1997, V3.0 for Windows 98 in 1998, V4.0 for Windows 2000 in 2000, and finally PowerPCB V5.0 in 2001 for Windows 2000 and XP. This era solidified the tool’s reputation for powerful, user-friendly PCB layout.
