Rigorous constraint management and rigid-flex technology.
PADS (Personal Automated Design System) is a widely-used PCB design software suite that has evolved over four decades through multiple corporate ownerships. Originally a DOS-based tool, it is now part of the Siemens EDA portfolio. mentor graphics pads version history
If you want to dive deeper into a specific version of PADS, tell me: Rigorous constraint management and rigid-flex technology
From a simple DOS PCB tool in 1986 to the modern, integrated platform of PADS Professional VX.2.14 in 2026, PADS has continuously evolved to meet changing industry demands. Whether using the classic PADS 9.5, the transitional VX series, or the latest PADS Professional under Siemens, the software remains an essential tool for PCB designers worldwide, balancing ease of use with powerful features.

: PADS was created by Gene Marsh and first released for the DOS operating system. At launch, it was positioned as an affordable option at roughly $495 per seat.
: Mentor shifted to the VX (Version X) nomenclature to align PADS with its high-end Xpedition technology.
Mentor gradually rebranded the software from PowerPCB to simply "PADS Layout" and "PADS Logic," standardizing version numbering into the 9.x lifecycle.
