TESSY - licensing FAQs

TESSY is available with a node-locked license, or with a floating license, or with a CI license.

The node-locked license restricts the use of TESSY to the PC the license is issued for. It is not a dongle license.
One or more floating licenses are administrated by a Floating License Server (FLS). At the same time, you may use TESSY as many times as the amount of licenses the FLS disposes over.

The Continuous Integration (CI) floating license is intended for TESSY in CI/CD pipelines. It allows TESSY only to run in headless mode, i.e. without using the graphical user interface. Only for Floating License Servers (FLS) on Windows. TESSY on Linux can use CI licenses of a FLS under Windows. At least one TESSY floating license of the same version must be present on the FLS.

Node-locked, floating, and CI license of TESSY include:

a. Maintenance for 6 months after purchase.
b. A license to use all combinations of microcontroller / cross compiler / debugger supported by your TESSY version.

Yes. If you dispose of a license for a certain TESSY version, this license is also valid for previous versions of TESSY. I.e. a license valid for TESSY V5.1 is also valid for e.g. TESSY V4.3 and lower versions.

Yes. A license is permanent (or perpetual). This means you can use TESSY with a given license as long as you want.

Yes. If it is technically possible (usually by VPN) you can access a remote TESSY Floating License Server (FLS) from anywhere in the world in order to obtain a TESSY license. E.g. a TESSY user located in India can use a TESSY license from a FLS located in Germany. This is legal, i.e. explicitly allowed by the licensing policy.

Yes. From the Floating License Server, a license can be transferred to another PC for a maximum of 30 days. This allows TESSY to be used on a PC not connected to any network. For the license transfer, it is not necessary for the remote PC to have access to the Floating License Server.

No. Renting or leasing of TESSY licenses is not possible.
