Rohde & Schwarz R&S VSESIM-VSS signal creation and analysis tool

Rohde & Schwarz has collaborated with Cadence Design Systems to develop the R&S VSESIM-VSS signal creation and analysis tool, aimed at simplifying the engineering process from RF design to implementation and enhancing accuracy by using realistic signals for both simulation and testing. It is useful for those in the wireless, automotive, and aerospace and defence industries as well as for manufacturers of active components and systems.

Supporting all major standards such as 5G, the latest Wi-Fi evolutions and more, the joint solution combines signal generation, design simulation and signal analysis to speed up the development process for RF components. As a result, developers and design engineers should benefit from an optimised tool that allows them to address design challenges earlier than before in the development process.

The tool functions as an addition to the Cadence Visual System Simulator (VSS) software for system simulation and modelling, particularly for RF components and RF assemblies used in wireless communications and radar design. The tool is designed to expand the capabilities of the VSS software by adding realistic signals to the workflow. It benefits from two established software tools from Rohde & Schwarz for testing operative circuits, modules and devices: the signal generation capabilities of the R&S WinIQSIM2 simulation software and the signal analysis capabilities of the R&S VSE vector signal explorer software. R&S VSESIM-VSS combines these functions and adds plug-ins for Cadence electronic design automation (EDA) tools.

The data sink plug-in from Rohde & Schwarz provides access to the signal at any point in the design process. The signal can be transferred to a vector signal generator and applied to available hardware, enabling system-level analysis of hybrid hardware/simulated implementations. Another important feature is support of direct digital predistortion (DPD) techniques to verify the effects of linearisation already in the simulation phase of power amplifier development.
