BoardSurfers: Installation Know-How: Cadence Licensing Floating vs. Single User

In PCB design teams today, the way licenses are managed can have a direct impact on productivity, infrastructure complexity, and how quickly engineers can get started.

Floating licenses have been the standard for years, mainly because they allow teams to efficiently share a common license pool. However, as workflows have shifted towards remote work, distributed teams, and increased mobility, this model can sometimes slow things down due to dependencies on VPNs, license servers, and network availability.

To support these changing needs, Cadence introduced Single User Licensing (SUL)—a simpler, workstation‑based licensing model that focuses on reliability and independence.

The biggest advantage of SUL is simple: your tools just work—anytime, anywhere. There is no need to connect to a license server or VPN, and no dependency on network availability. Whether you are traveling, working remotely, or in a low-connectivity environment, you can access your Cadence tools without interruption.

This post kicks off the Cadence SUL Series, where we will walk through what SUL is, where it fits, and how it can simplify your day‑to‑day work.

What Is Cadence Single User Licensing (SUL)?

Cadence Single User Licensing is designed for one user on one machine, giving you dedicated and uninterrupted access to your Cadence tools.

It is well-suited for engineers working on personal or remote workstations, or anyone who prefers a setup that simply works without relying on a network license server.

What Sets SUL Apart

• Work on the Go – No Connection to a Corporate License Server Needed: One of the biggest advantages of SUL is its flexibility. Whether you are traveling, working from home, or at a customer site, your tools remain fully available.
  No VPN. No server check-ins. No connectivity concerns.
• Dedicated Access: Each user has their own license, so there is no contention or waiting when launching tools. 
• Simple Setup: There is no need to install or configure a FlexNet license server. Activation happens during installation, making the setup quick and straightforward.
• Cost Predictability: Licenses are tied to individuals rather than shared pools, making it easier to plan and manage costs, especially for smaller teams.

Floating License vs. Single User License: What Works Best?

If you are using Cadence tools such as OrCAD X PCB Editor, OrCAD X PCB Layout, or OrCAD X Capture, the license model you choose can affect your workflow. Floating licenses work well for teams that benefit from shared access, while SUL is better suited for individuals who need consistency and independence.

Here’s a quick comparison:

Conclusion

Single User Licensing is not just an alternative licensing model—it is a practical option for engineers who want a more predictable and flexible way to work. By removing dependencies on license servers and network access, SUL helps keep workflows simple and consistent, especially in remote or mobile environments.

Currently, SUL is available for selected OrCAD X products, including OrCAD X Capture, OrCAD X PCB Editor, OrCAD X PCB Layout, and PSpice A/D.

In the next post in this series, we will walk through the installation and activation steps so you can get up and running quickly.
