In 2015, Mentor Graphics restructured the brand into three distinct tiers based on complexity:
The software began its life in the 1980s under CAD Software, Inc. localized in Littleton, Massachusetts.
Visual verification and high-speed differential pairs.
Introduced the ability to save an existing layout segment (components and traces) and replicate it across multiple areas of the board or in different designs. mentor graphics pads version history

Introduced high-speed analysis, RF/microwave circuitry implementation, and early Design for Fabrication (DFF) checking. The PADS 9.x Series
Focuses on cloud integration, PartQuest partnership, collaborative design review, and DFM improvements. Conclusion In 2015, Mentor Graphics restructured the brand into
PADS Version 5.0, released in 2002, marked a significant upgrade to the software. Key features included:
PADS is a suite of PCB design tools typically comprising three core components: (Schematic Capture), PADS Layout (Board Design), and PADS Router (Interactive/Automatic Routing). Known for its intuitive user interface and "what-you-see-is-what-you-get" approach, PADS became the industry standard for mid-market design.
Focused on stability after the Mentor acquisition. It improved copper pour generation and dxf importing. Introduced the ability to save an existing layout
The company was briefly sold to Japanese manufacturer Kyoden before being merged into Innoveda (a venture between Viewlogic and other capital) in 2000. Mentor Graphics Era (2001–2017)
Expanded memory allocation limits to utilize 64-bit Windows architectures more efficiently, allowing the software to handle massive layer counts and high-density interconnect (HDI) designs.
Early versions focused on basic 2D layout for double-sided or 4-layer boards.
More flexibility in layout constraints.
This release emphasized performance and advanced design capabilities, including:
