Mentor Graphics Pads Version History ((new)) ●
The history of PADS PCB design software spans over four decades, evolving from a DOS-based tool into a sophisticated suite now under the Siemens EDA PCB Libraries Origins and Early Years (1980s–1990s)
: PADS was first released by Gene Marsh and his son as a DOS-based operating system tool, originally priced at approximately $495 per seat. mentor graphics pads version history
If you need a specific version’s release notes or bug fix details (e.g., PADS 9.5 vs. VX.2.7), let me know and I can provide deeper technical comparisons. The history of PADS PCB design software spans
The version history of Mentor Graphics PADS (now part of Siemens EDA) reflects its evolution from a standalone PCB tool to a multi-tiered design ecosystem. 2022 Release: Sketch Routing
The software’s journey is marked by key acquisitions that integrated advanced simulation and layout technologies: 1986: Founded by Gene Marsh as PADS Software.
Innoveda and Mentor Acquisition (2000–2001): Kyoden sold PADS to Innoveda, which was subsequently acquired by Mentor Graphics in 2001.
- 2022 Release: Sketch Routing. A predictive routing technology where you draw the "path" and the AI fills in the actual traces.
- Constraint Manager: A spreadsheet-style interface for high-speed rules (matched length, propagation delay, pin-pair rules) that previously only existed in Allegro.
- PADS Standard Plus (Current): Retains the legacy 9.5/VX codebase for smaller boards (< 500 pins).
- PADS 5.0 (1998): This version introduced a new graphical user interface (GUI) and support for Windows NT.
- PADS 6.0 (2001): This release added support for 64-bit processors and improved performance.
- PADS 7.0 (2003): This version introduced a new netlist-based design flow and improved collaboration capabilities.
