The mid 2000s to late 2000s saw the release of PADS 6.0, 7.0, and 8.0, which continued to build on the software's capabilities. Version 6.0 introduced support for advanced high-speed design, including automatic tuning and optimization. Version 7.0, released in 2006, added support for design for manufacturability (DFM) and design for assembly (DFA). Version 8.0, released in 2008, featured improved collaboration capabilities and support for 64-bit operating systems.

The first version of PADS, version 1.0, was released in the early 1980s by PADS, a company founded by three engineers in the United States. The software was initially designed for MS-DOS and provided basic PCB design capabilities, including schematic capture, component placement, and routing. Over the next few years, PADS released several updates, including version 2.0, which introduced support for hierarchical designs and version 3.0, which added capabilities for high-speed design and simulation.

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.

The late 1990s and early 2000s saw the release of PADS 4.0 and 5.0, which introduced significant enhancements to the software. Version 4.0 featured improved performance, enhanced user interface, and support for larger designs. Version 5.0, released in 2001, added support for System-On-Chip (SoC) designs, high-speed design, and signal integrity analysis.

Mentor Graphics PADS is a popular printed circuit board (PCB) design software that has been widely used in the electronics industry for decades. The software has undergone significant changes and improvements over the years, with each new version offering enhanced features, capabilities, and performance. In this article, we will provide a comprehensive overview of the Mentor Graphics PADS version history, highlighting the key developments, milestones, and innovations that have shaped the software into what it is today.

In 2015, Mentor Graphics released PADS OrCAD, a comprehensive PCB design solution that integrated PADS with the OrCAD schematic capture and simulation tools. This release marked a significant shift towards a more integrated design flow. Later, in 2017, Mentor Graphics released PADS Xtreme, a next-generation PCB design platform that featured a modern user interface, improved performance, and enhanced capabilities for high-speed design, simulation, and collaboration.

The early 2010s saw the release of PADS 9.0 and 10.0, which marked significant milestones in the software's evolution. Version 9.0, released in 2010, introduced a new user interface, improved performance, and enhanced support for high-speed design. Version 10.0, released in 2012, added support for 3D design, advanced simulation, and integration with other Mentor Graphics tools.
