Access to Cadence & Synopsys Tools

Students in Electrical Engineering and Computer Science (EECS) courses have a few options available that provide access to Cadence and Synopsys tools for their coursework:

Access using the Linux Remote Login Service

The license terms for both Cadence and Synopsys software restrict remote network access to primary residences in the United States that are within a 50-mile radius of U-M Ann Arbor’s North Campus. In addition, logging into the Linux Remote Login Service to access the software will require students to authenticate with their U-M uniqname & UMICH password, and use of Duo two-factor authentication.

In order to be allowed remote access to Cadence or Synopsys, students will need to do the following:

After you have completed the tasks above, it may take up to two business days before your access is authorized to run the software using the Linux Remote Login Service. After logging in with your uniqname, UMICH password, and verification with Duo two-factor authentication, you will be able to run Cadence and Synopsys commands as though you were sitting directly at a CAEN Linux workstation.

If you received access to Cadence or Synopsys for course use, your access to run them over the network from home will be removed at the end of the term.

Common Questions about using Cadence & Synopsys Remotely

Why is Duo two-factor authentication necessary for logging in?

The license terms require additional, more protective security safeguards than just a password alone. This requirement is met by the use of Duo two-factor authentication.

I don’t have my Duo-enrolled device with me, can I still log in and use Cadence or Synopsys?

Yes. You can call the ITS Service Center (734-764-4357) for assistance. After you prove your identity, ITS support staff can issue you temporary passcodes which you can use to log in for up to 12 hours. ITS recommends that you enroll more than one device in case there are issues with using your primary device.

Unable to log in? Getting an error message?

If you are unable to login, send an e-mail to Include information about how you are trying to log in, the name of the computer to which you are trying to connect, which software you are using, as well as what you observe (such as any error messages). Be sure to send the e-mail from your University of Michigan e-mail address ending in
