Signal creation and analysis tool speeds RF component development
Electronic test equipment maker Rohde & Schwarz (R&S) and computational software company Cadence Design Systems say they have collaborated on a solution aimed at simplifying the engineering process from RF design to implementation and enhancing accuracy by using realistic signals for both simulation and testing.

The R&S VSESIM-VSS signal creation and analysis tool is designed to speed up the development process for RF components. It is offered as being particularly useful for users in the wireless, automotive, and aerospace and defense industries, as well as for manufacturers of active components and systems.

Supporting all major standards such as 5G, the latest Wi-Fi evolutions, and many more, the joint solution combines signal generation, design simulation, and signal analysis, building on the strengths of each company's popular and proven solutions. As a result, say the companiess, developers and design engineers benefit from an optimized tool that allows them to address design challenges earlier than before in the development process.

The R&S VSESIM-VSS signal creation and analysis tool functions as an addition to the Cadence Visual System Simulator (VSS) software, a well-established solution for system simulation and modeling, particularly for RF components and RF assemblies used in wireless communications and radar design. R&S VSESIM-VSS from Rohde & Schwarz is designed to expand the capabilities of the VSS software by adding realistic signals to the workflow, increasing simulation accuracy and simplifying the design process.

R&S VSESIM-VSS 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. An key feature of R&S VSESIM-VSS is support of direct digital predistortion (DPD) techniques to verify the effects of linearization already in the simulation phase of power amplifier development.
