Mentor Graphics Pads Version History [new] Jun 2026

: Headquartered in Marlborough, MA, the company grew rapidly, becoming a primary competitor to early leaders like PCAD and Calay Systems.

: PADS was first released by Gene Marsh and his son as a DOS-based operating system tool, originally priced at approximately $495 per seat.

AI-driven routing, cloud-native PLM syncing, and rigid-flex automation. mentor graphics pads version history

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)

Introduced in the late 1980s by CADAM, PADS-PCB and PADS-2000 were among the first professional PCB design tools available for DOS-based personal computers. They offered basic schematic capture and manual routing capabilities, breaking the monopoly of expensive Unix workstation tools.

In recent years, Mentor Graphics has continued to evolve PADS, releasing version 9.0, which introduced a new, more intuitive user interface. This version also featured improved collaboration tools, enabling designers to work more effectively with global teams. Additionally, Mentor Graphics introduced Xpedition, a next-generation PCB design platform that integrates PADS with other Mentor Graphics tools, such as HyperLynx and FloTHERM.

Implementation of advanced EDMD (IDX) protocols for real-time, bi-directional collaboration with mechanical design suites like Siemens NX and SolidEdge.

3. The Modern Era: PADS Professional and PADS Standard (2014–Present)

The classic “PADS Standard” still exists for smaller boards (up to 16 layers). “PADS Professional” now shares the same database engine as Xpedition Enterprise.

Substantially upgraded the constraint management system. High-speed design constraints (like DDR memory topologies) could now be defined once in the schematic and driven seamlessly through to layout. 4. The Siemens Era: PADS Professional Premium

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)
