Licensing

What is the difference between a FLEXlm node-locked license and a floating license?

TimingDesigner® offers two licensing methods through FLEXnet from Macrovision: a node-locked method using a FLEXid hardware key and a floating method. Both methods require the FLEXnet License Manager to be running, configured using the TimingDesigner license file issued at the time of purchase, and be accessible to the machine requesting the license.

The differences between the two are as follows:

Node-Locked – The node-locked method is restricted to Windows based machines, uses either a parallel port or a USB port FLEXid hardware key, and requires the license manager (and therefore the hardware key) be installed on the same machine as that requesting the license. The proper FLEXnet device driver must be installed in order for FLEXnet to read the appropriate port. If the key can be read and is determined valid the tool will start. Otherwise, the license manager will fail to grant the license request and FLEXnet will continue its sequential search for another license server. By definition, a node-locked method cannot be shared or accessed across a network connection! This is a limitation imposed by TimingDesigner and not FLEXnet.
Floating – The floating method only has the restriction there be a valid license available for check out. If the license manager is configured to use a floating license, the license request will be granted based on the validity of the license and the number of seats available. The license server can be the same machine that is running the application or can be anywhere on the network. If a license checkout is successful the tool will start. Otherwise, the license manager will fail to grant the license request and FLEXnet will continue its sequential search for another license server.

For more information on FLEXnet device drivers, see the Support Solutions document entitled TimingDesigner Can't Read my Hardware Key in the TimingDesigner knowledge base inside the EMA Resource Center (ERC).
