PathWave System Design software bundles provide system engineers with a choice of value-packed, pre-configured combinations of software built for specific system design challenges. These combinations provide up to three different simulation technologies: RF systems, communications/digital signal processing, and phased array analysis. There are also several add-on elements that add powerful features to the system design workflow as well as libraries that enable system-level design and verification for specific industry applications such as radar/EW and cellular communications.

PathWave System Design Verification Libraries

Baseband verification libraries provide compiled sources, receivers, function blocks, and reference designs that adhere to the physical layer of current and emerging specifications. They are used to create, examine, and receive PHY waveforms and test vectors at various locations in a system diagram in order to exercise system architectures and algorithms, down to the block level. With native TCP/IP connectivity, they also support co-design with test equipment and hardware development boards for both baseband and modulated-carrier signals.

PathWave System Design Exploration Libraries

Exploration libraries build on top of Verification libraries. They provide an open platform for innovative PHY designs that includes working, native source code for PHY blocks (math format), plus documentation on the standard itself. This gives system architects and algorithm developers a head-start on innovative implementations of new platforms, as well as an open gold-standard for comparison. Exploration libraries are polymorphic, incorporating compiled models for simulation speed, as well as open to user-supplied IP, for easy comparison. For designers working at the cutting edge of emerging standards, they are also a tremendous learning tool and productivity aid. Special licensing and support consideration apply. Please inquire with your Keysight sales representative for more information.

Cooperative Licensing with Signal Studio

The most recent versions of Keysight Signal Studio now offer an option to “Export to Keysight Simulation”. Encrypted .WFM waveform files that are exported using this new option retain their Signal Studio licensing, but become available for use in PathWave System Design dataflow simulations, depending on the type of license available on that simulation host.

Look for Signal Studio Option 7FP (fixed perpetual license on a nodelocked host/source) or Option 7NP (floating license). See the Signal Studio software products for more details.


PathWave System Design baseband reference libraries can be added to any System Design environment or bundle.
