Rohde & Schwarz and Cadence have collaborated on a solution aimed at simplifying the engineering process from radio frequency (RF) design to implementation and enhancing accuracy by using realistic signals for both simulation and testing.
The new R&S VSESIM-VSS signal creation and analysis tool can speed up the development process for RF components. The company says it’s particularly useful for customers in the wireless, automotive, and aerospace and defence industries as well as for manufacturers of active components and systems.
New wireless and satellite technologies offer ever wider frequency ranges and involve increasingly demanding requirements. Using the same signal creation methods and analysis algorithms as for subsequent hardware testing enables direct result correlation from the early design stages to implementation verification, allowing conclusive and consistent analysis of widely used key performance indicators such as error vector magnitude (EVM).
To this end, Rohde & Schwarz has collaborated with Cadence Design Systems, Inc. to develop the R&S VSESIM-VSS signal creation and analysis tool, which supports 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, the result of which is an optimized tool that allows developers and design engineers to address design challenges earlier than before in the development process.
Christina Gessner, Vice President Spectrum & Network Analyzers, EMC and Antenna Test at Rohde & Schwarz said, “Connecting EDA design simulation and test and measurement help our customers achieve first-pass design success and shorter times to market. Using realistic signals, deriving common figures of merit such as EVM and understanding linearization capabilities even before tape-out means a competitive advantage for our customers. We look forward to bringing the results of our cooperation with Cadence to the market”.
The R&S VSESIM-VSS signal creation and analysis tool functions as an addition to the Cadence® Visual System Simulator™ (VSS) software, a solution for system simulation and modelling, 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 uses two 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 added feature of R&S VSESIM-VSS is the support of direct digital pre-distortion (DPD) techniques to verify the effects of linearization already in the simulation phase of power amplifier development.
