Keysight EEsof EDA Licensing Options

License types

Keysight EEsof EDA provides software products in either a floating or node locked license configuration. Node locked and floating licenses are available either as perpetual or time based products. 

Product structure

Keysight EDA product structure consists of licensed elements and bundles. A bundle is a collection of licensed product element(s) designed to service a user’s workflow. A bundle includes a product environment (UI) and numerous packaged features, and is a cost effective way of providing a broad range of capabilities to a user at an attractive price. Any feature accessed in a bundle will reserve the rest of the features in that bundle for the specific user. An element is a collection of feature(s) designed for a specific task (e.g. a harmonic balance simulator element), and is typically used to extend product capability. An element reserves all features contained within it for the specific user. 

License counting or job control

All Keysight EDA licenses are counted at the product license level. Simulators and certain models/libraries are counted job controlled features—a fixed count is assigned to the feature to regulate concurrent usage of the license. GUI features are not job controlled, and users can have multiple UI windows opened up simultaneously if they want. 

Multi-core CPU support

 Keysight EDA utilizes job control to manage concurrent feature usage (as opposed to CPU core counting). This enables users to exploit the capability of multi-core computers without needing additional licenses. Remote and distributed simulation is supported. If a user has a floating license, the user may run a simulator feature that is part of a product bundle on a remote host.

Remote and distributed simulation

 For cost effectiveness, special product elements have been constructed to speed up simulation “sweeps”. These elements act as simulation accelerators. They consist of a distributed “N” pack (N is the number of parallel jobs that can be run) licenses which simulate as children alongside a standard simulator license. Distributed N pack licenses cannot run without a standard simulator license. LSF and Grid compute cluster managers are supported with distributed N packs along with job queuing. Generally speaking, distributed simulation “N” packs are effective in those cases where a sweep needs to be done and each sweep point takes more than 5 minutes to simulate. Please refer to applicable product documentation for more detailed information.
