Mentor Graphics Pads Version History -
Early versions focused on basic 2D layout for double-sided or 4-layer boards.
The transition period. Siemens focused on bridging PADS (mid-tier) with its high-end Xpedition Enterprise tool.
The product's stability fluctuated during the Innoveda years before Mentor Graphics' acquisition provided a more robust corporate backing.
The history of PADS (Personal Automated Design System) is a decades-long journey that mirrors the evolution of the entire electronic design automation (EDA) industry. From its origins as a budget-friendly DOS application to its current status as a sophisticated suite under Siemens, PADS has remained a staple for independent engineers and small-to-medium design teams. 1. The Early Era: PADS-PCB and the DOS Roots (1985–1990s) mentor graphics pads version history
Released to modernize the installation and database structure, PADS 9.4 updated ASCII formats for Layout and Router while maintaining library compatibility. The Modern VX Era: 2014 – Present
Introduced the ODB++ manufacturing format as a standard output, reducing reliance on fragmented Gerber files.
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) Early versions focused on basic 2D layout for
In 2002, Mentor Graphics acquired PADS Software Inc. The acquisition aimed to bridge the gap between Mentor’s high-end enterprise tools (like Board Station and Expedition) and the mainstream desktop market.
: The first version, PADS-PCB , debuted for DOS. At just $495 per seat, it democratized PCB design, which was previously locked behind expensive, proprietary Unix workstations.
From a modest DOS program in 1986 to a cloud-connected professional suite in 2025, the history of Mentor Graphics PADS is a remarkable journey. We've seen the birth of PowerPCB, the legendary stability of PADS 9.5, and the powerful technological leap of the VX series. While the brand may have changed hands and the interface may have evolved, PADS remains a testament to accessible, high-performance PCB design, empowering engineers to bring their most complex electronic ideas to life. The product's stability fluctuated during the Innoveda years
Whether you are a veteran clinging to PADS 9.5 or a student learning on VX.2.15, you are using software that has shaped the electronics of the last 40 years. From automotive ECUs to IoT sensors, the "people's PCB tool" continues to route the world.
These updates introduced advanced physical design rules for high-speed routing, such as differential pairs, trace length matching, and conditional design rules.
), spans over 30 years and transitions from a standalone desktop PCB design tool to a sophisticated suite integrated with high-end enterprise technology. Siemens Blog Network Origins and Early Acquisitions Early 1990s
