Mentor Graphics Pads Version History (2027)

As PCB technology advanced—driven by smartphones and IoT—PADS had to evolve from a simple layout tool to a high-speed design environment.

Mentor shifted to a "dot" release format (9.0, 9.1, 9.2, 9.3, 9.4, 9.5). This was the most stable era of the software.

The Paradigm Shift: PADS Professional and Standard (2015–2018) mentor graphics pads version history

Understanding the version history of PADS highlights the evolution of modern PCB design, tracking the industry's shift from basic manual routing to high-speed, constraint-driven AI automation. The Early Era: DOS to PADS-Perform (1980s–1990s)

The product's stability fluctuated during the Innoveda years before Mentor Graphics' acquisition provided a more robust corporate backing. As the electronics industry continues to evolve, with

Introduced a centralized Constraint Manager shared dynamically between schematic and layout.

As the electronics industry continues to evolve, with emerging technologies like IoT, artificial intelligence, and 5G, Mentor Graphics PADS remains a vital tool for designers and engineers. Looking ahead, we can expect PADS to continue to innovate, incorporating emerging technologies like machine learning, cloud-based collaboration, and advanced simulation capabilities. Mentor Graphics revived the "PADS" name

A revolutionary shift. It combined the PADS interface with the powerhouse Xpedition routing technology. This brought high-end features like sketch routing, rigid-flex design, and real-time 3D DRC to the desktop market. PADS VX.2 Generation (2016–2020)

In 2002, PADS Software Inc. was acquired by , a much larger EDA giant. This acquisition would permanently change the product's trajectory. Although Mentor Graphics acquired the company in 2002, the first fruits of this merger were seen in 2003. Mentor Graphics revived the "PADS" name, which it had inherited through its acquisition of Innoveda (a firm that had previously consolidated PADS and ViewLogic). To differentiate it from its high-end Expedition tools, Mentor positioned this revamped PADS suite for the low- to mid-range PCB layout market.

Mentor Graphics launched the platform, built on the robust Central Database technology borrowed from their enterprise-level Xpedition software.

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. Early Era & Expansion (1980s – 2000s)
