SystemVue Release Notes

Release Highlights: W1461 SystemVue Core Platform

Workspace Compatibility and Workspace Conversion Tool

In SystemVue , the workspace format has been updated for usability improvement and this update introduces workspace incompatibility. The workspaces created using the previous SystemVue releases are automatically converted when they are opened in SystemVue . The original workspace is not modified unless you overwrite it by saving (File > Save) the converted workspace.

The workspaces created using SystemVue are incompatible with previous SystemVue releases. You can use the following tools, available under the <SystemVue_Install_Directory>\bin directory, for converting workspaces between SystemVue and previous releases:

  • WorkspaceCoversionTool.exe: convert a workspace created in previous SystemVue releases to SystemVue compatible format.
  • WorkspaceBackwardConversionTool.exe: convert a SystemVue workspace to the the format that are compatible with previous SystemVue releases.

The command line syntax of the conversion tools is described in the line below:
WorkspaceConversionTool.exe "SourcePath" "DestinationPath"

For example:
WorkspaceConversionTool.exe "C:\Examples\WorkspaceA_For2013_01.wsv" "C:\Examples\Converted\ConvertedWorkspaceA_For2013_08.wsv"
WorkspaceBackwardConversionTool.exe "C:\Examples\WorkspaceB_For2013_08.wsv" "C:\Examples\Converted\ConvertedWorkspaceB_For2013_01.wsv"

SystemVue Engine with Programming API

In SystemVue , a new standalone data flow simulator, called SystemVue Engine, is introduced. SystemVue Engine is used for distributed simulations and for co-simulation with other simulators like ADS and GoldenGate circuit simulators (see Verification Test Bench). The SystemVue Engine executable, SystemVueEngine, can be called from command line to run Data Flow Analyses in SystemVue workspaces. Advanced users can write C++ programs through the programming API to control System Vue Engin e. For more information about SystemVue Engine programming API, refer to the Programmer's Guide in SystemVue Help.

For SystemVue Windows installation, the SystemVueEngine executable comes with the SystemVue Windows installer and is located in the bin directory under SystemVue installation directory. In addition, SystemVue contains two examples that use the SystemVue Engine programming API:

  • SVEClientExample: a simple command line program to run a SystemVue workspace, located in \Examples\Tutorials\Simulation_Control_and_Scripting\Scripting\SystemVueEngine\SVEClientExample under SystemVue installation directory.
  • SVETester: a GUI demonstration application for running SystemVue workspaces, located inside \bin under SystemVue installation directory.

SystemVue Engine also supports 64-bit Linux platform. The 64-bit SystemVue Engine Linux installer is available on the SystemVue download website. On Linux platform, the SystemVueEngine is located in the bin directory under the installation package.

SystemVue Engine saves simulation results as ADX files (an HDF5 compatible file format). An ADX file can be imported into SystemVue as a dataset in the workspace tree, using File > Import > ADX File....

While each seat of the SystemVue environment already includes 1 license of this data flow simulator, additional concurrent SystemVue Engines can be enabled by purchasing the W1711 add-on product (see W1711 SystemVue Engine below).

Distributed Simulation

SystemVue supports distributed simulation for Data Flow Analysis and Sweep of data flow analyses using the following modes:

  1. Parallel runs on local computer – Simulations will be executed outside SystemVue environment using SystemVue Engine on the local computer.

    Make sure SystemVue is installed in a directory path containing only ASCII characters in order to use "Parallel runs on local computer" mode.

  2. Platform LSF – Simulations will be executed using SystemVue Engine on machines from a Linux LSF cluster.

Distributed simulations are launched and monitored by the Simulation Manager – a distributed simulation utility tool among EEsof products. In the Platform LSF mode, the Simulation Manager uses Platform LSF to distribute and schedule simulation jobs across machines under the LSF cluster. On the other hand, when the distributed platform is set to the local computer, the Simulation Manager launches multiple simulation jobs in parallel to utilize multi-core (multi-processor) capabilities on the local computer and relies on the local operating system to perform job scheduling.

For a distributed sweep simulation, individual sweep points are run in parallel using SystemVue Engine, either on the local machine (Parallel runs on local computer) or on multiple machines in the LSF cluster (Platform LSF). After simulation, SystemVue merges distributed sweep results into a single sweep dataset in the workspace tree, similar to how a sweep is run inside the SystemVue environment.

A Data Flow Analysis can also use this feature to launch a standalone SystemVue Engine process outside the SystemVue environment (Parallel runs on local computer), or run a simulation remotely on a remote machine from an LSF cluster (Platform LSF).

Distributed simulation is not supported when SystemVue is installed on a Windows XP.

Verification Test Bench

A VTB (Verification Test Bench) is a SystemVue Data Flow design that can be used to verify the performance of a circuit design in its design/simulation environment (ADS or GoldenGate). The benefits of using a VTB is that the performance of the circuit design can be verified using real world complex modulated signals conforming to wireless standards such as 2G/3G/4G. VTB is simulated in ADS and GoldenGate using the SystemVue Engine. Refer to Verification Test Bench for details about the creation and validation of VTBs and also refer to Verification Test Bench Tutorial.

VTB examples are provided to analyze LTE and WLAN 802.11ac transmitter and receiver characteristics. The example workspaces are available in the example directory: <SystemVue_Install_Directory>/Examples/VTB. For more information, see VTB Workspaces.

SystemC Model Library and SystemC Analysis

In SystemVue , two new features related to SystemC Modeling are introduced:

  • SystemC Model Library: An automatic mechanism to bring custom SystemC models inside SystemVue as SystemC model libraries. With this flow, custom SystemC models can be used in the same way as regular SystemVue models. Refer to SystemC Model Library for detailed information.
  • SystemC Analysis: A new SystemC simulation capability for simulating designs (schematics) containing only built-in SystemC models and custom SystemC models (created using the SystemC Model Library flow). Refer to SystemC Analysis for detailed information.

Other Platform Updates

  • Analysis dataset names now default to blank, which automatically constructs a dataset name based on the current analysis, design, and configuration names (if any), in the form: Analysis_Design_Config_Data.

    If left blank, the dataset name changes automatically if you rename an associated item. In addition, any existing dataset (with the old name) is retained for data comparison purposes.

  • CommandExpertLink now supports Command Expert 1.2.
  • SystemVue - Riviera Pro cosimulation supports only Riviera Pro 2013.02 and later.
  • HDL and XilinxIPIntegrator also support cosimulation with Questa TM.
  • New models SignalDownloader_M8190Env and SignalDownloader_M8190Env_1CH are introduced to support M8190 DUC (Digital UpConversion).
  • M8190 in Waveform Sequence Composer is also updated to support DUC.
  • Graph Series Wizard supports a new series type: Sample and Hold – Y vertex value is held till the next vertex.
  • PulseGen now supports optional trigger input.
  • New model PassiveMixerBB is introduced to support passive mixer with real baseband signal.
  • SpectrumAnalyzer now supports Hamming window.
  • The Add file button in HDL model now remembers the last selected directory.

Release Highlights: Add-on Libraries and Design Kits

W1711 SystemVue Engine (New Product)

Systemvue's data flow simulation engine is now available separately as a standalone simulator on either Windows or Linux/64 operating systems. While each seat of the SystemVue software already includes a license for 1 data flow simulation instance, the standalone systemVue Engine can also be used for additional concurrent local simulations; for distributed computing using W1712 (see W1712 Distributed Simulation 8-pack below); and scripting.

W1712 Distributed Simulation 8-pack (New Product)

In SystemVue , a new Distributed Simulation capability is introduced. It is designed to support sweep evaluation when the simulation for each sweep point takes a long time to run. For more information, refer to Distributed Simulation and Licensing for Distributed Simulation.

W1719 RF System Design Kit (Spectrasys) Enhancements

High Carrier Count Intermods

You can now simulate nonlinear responses to hundreds of RF carriers with an innovative simulation technique. Traditionally, industries using many RF carriers, like TV, use simplified equations to predict nonlinear performance limited to in-band interference only. This new technique is fast and covers both in‐band and out‐of‐band distortion simulation. You can now simulate hundreds of carriers.

For more information, see High Carrier Count Intermods

Residual Phase Noise

Several active devices now support residual phase noise. This noise is additive phase noise that is added noncoherently with any input phase noise. The models that support residual phase noise are:

Nonlinear Switch Updates

The nonlinear switch models now support more parameters so that signals appearing at other switch pins can be used to generate intermods.

New RF Architecture Examples

  • RF Amp Residual Phase Noise.wsv
  • Simple CATV Amplifier.wsv
  • Switch Intermods.wsv

W1716 Digital Pre-Distortion Builder Updates

  • A new option Enable Power Backoff is added in DPD Setting. If this option is enabled, the PA input power will be backed off, i.e. the PA input power with DPD in Step 4 would be lower than the original PA input power without DPD in Step 1. If this option is unchecked, the PA input power will be kept the same, i.e. there is no power backoff. This option is only active when Model Type is selected as Memory Polynomial or Volterra Series. For Look-Up Table, this option is hidden and always enabled. If this option is enabled, the whole process is the same as in previous release (i.e. SystemVue 2013.01).

    If this option is unchecked ( i.e. there is no power backoff), there is no need to re-download the original signal in Step 5. Since the input power is the same in Step 4 and Step 2, we can just compare the results in these two steps to verify DPD response. Similarly, when Current Iteration ≥ 2, there is no need to re-capture the PA output with DPD in Step 2, because the signal is the same as which captured in Step 4 of the previous iteration.

  • A Get PA Characteristics button is added in Step 2 in the manual DPD UI. Click this button to run the analysis and get PA characteristics from the captured PA input and output data in Step 2. Similarly, a Get DPD-PA Characteristics button is added in Step 4.
  • A PAPR button is added in Step 4 to show the PAPR of the pre-distorted signal.

W1717 Hardware Design Library Enhancements

  • On <TOPHDL>_CosimWrapper.v(hd), a new clock enable signal "ce" is added that can control all sequential logics of generated HDL. Automatic Xilinx and Altera FPGA flow now uses <TOPHDL>_CosimWrapper.v(hd) as top level design. Users can use the new added ce signal to control all sequential logics of generated design.

Release Highlights: Licensing

  • SystemVue 2013.08 requires: a) version 2013.05 of the EEsof EDA licensing software and b) version 3.1 codewords to run.
  • A real-time and systematic license setup troubleshooting utility is added to the License Manager tool’s Diagnose tab. This utility also produces a detailed health report of the configuration.
  • SystemVue does not automatically release licenses after checking out. In SystemVue 2013.08, there is a new menu button Action > Release All Simulation Licenses for users to manually release all checked out simulation licenses.
  • LTE-Advanced Baseband Verification Library usage usually requires the sv_mdl_lteadv and sv_mdl_lte licenses because the top level models like Source/Receiver have LTE models inside the sub-circuits. Earlier, it required the sv_mdl_ltea license only. LTE Baseband Verification Library does not work with sv_mdl_lteadv license, earlier it used to work. For more details, refer to SystemVue Product Dependencies.

Resolved Issues

SystemVue Platform and Models

  • SData model has been updated to handle simulation sampling rate that is other than two times of the maximum frequency component in the S parameter, when the input is a real signal with characterization frequency equal to 0.

Licensing

  • The EEsof EDA License Tools version is 2013.05. Licensing vendor daemon (agileesofd) is upgraded to sync up with FlexNet FNP 11.9.1 version of FLEX license manager (lmgrd). SystemVue installer for the Windows platform will automatically set up these two new license server daemons by default for the local node-locked license users. For more details, refer to Licensing (For Administrators).
  • On windows, a possible Administrator privilege issue preventing the automatic restarting of the FlexNet license server program, lmgrd, after the PC comes out of the hibernation mode has been fixed. The FlexNet license server is now automatically restarted without any user intervention.

Known Issues

Licensing Known Issues

  • SystemVue 2013.08 requires EEsof Licensing Tools version 2013.05 or later. It will not work with older EEsof Licensing Tools versions like 2013.01 or earlier.
  • There is a known Flexera FNP issue, whereby mixing node-locked codewords and floating codewords in one license file can result in: a) Remote simulations not working or b) A second local simulation not working in case the license is node-locked and also has incorrect version.
    Workaround: It is strongly recommended that you do not mix node-locked codewords and floating codewords in one license file nor in any configuration that ends up with node-locked codewords and floating codewords both available on the same server. In other words, put the node-locked license and the floating license on different servers, and point to the respective one based on what you need to run.
    Additionally, we also recommend you to remove expired codewords, to separate out the new and the old versions of codewords into different files and different servers, and to point to the respective one based on what you need to run.
  • On the Linux platform, SYSTEMVUE_LICENSE_FILE needs to be correctly specified before starting SystemVue. Without that being set correctly, SystemVue would not start.
  • Not specifying the TCP/IP port for the license server during license setup may lead to unexpected behavior and/or license checkout failure on the Windows platform. We strongly recommend you to always explicitly specify the TCP/IP port associated with each license server.
  • A node-locked or floating bundle cannot be shared between SystemVue 2013.08 and SystemVue 2011 or earlier releases when run at the same time.
  • The "Check-in failed" message occurs in the license activity log occasionally can be ignored; the license mentioned in this message is properly returned.
  • License Setup Wizard does not remove any previous user-configured FLEX Windows License Service installed using FlexNet's lmtools.
    Workaround: You must remove the previous user-configured Windows License Service via lmtools.
    • Run the lmtools.exe from C:\Program Files\Agilent\EEsof_License_Tools\bin to invoke the lmtools utility. The lmtools utility window is displayed.
    • In the Service/License File tab, check the Configuration using Services option. All user-configured FLEX Windows License Services will be listed.
    • Select the service you wish to remove.
    • Select the Config Services tab and click the Remove Service button to remove the service.
      To ensure that the license service or lmgrd is running, click View Log. A log window appears that confirms whether agileesofd and lmgrd are up and running.
  • While running multiple versions of prior SystemVue releases together, set SYSTEMVUE_MAXIMUM_BUNDLE_USAGE=ON in your environment so that all of them will use the same method to check out licenses. Otherwise, you might receive an error message, "Licensed number of users already reached".
  • On some Windows 7 machines, when more than one definition of an Ethernet adapter exists (duplicates), license checkouts may appear to hang up.
    Workaround: Disable the duplicate network card definitions in your network settings: Control Panel > Network and Internet > Network Connections. This issue has been acknowledged by Flexera and they have created a bug report (SIOC-000103097).
  • If a license server is configured with two license versions, that is, version 2.8 and 2.9 node-locked license files, the license server may crash.
    Workaround: You should combine the two license files into one file, instead of using them separately.
  • For LSF style distributed simulations, in case of windows, ensure that the PATH points to the $HPEESOF_DIR/EEsof_License_Tools/${architecture} directory that corresponds to the EEsof release being used. This will ensure that the proper version of the Flexera utilities (like lmutil) gets picked up in the path before any older incompatible versions (that may also be installed on a users’ system.)
  • License Setup Wizard (aglmwizard.exe), which is used to set up and record the license path would not work on Linux platform if you already have an environment variable set for SYSTEMVUE_LICENSE_FILE.
    Workaround: You can use SYSTEMVUE_LICENSE_FILE variable to point to license file or refer to Licensing (For Administrators).
  • On windows, FlexFNP license server program, lmgrd, may not be automatically restarted during EEsof application startup after PC comes out of the hibernation mode; instead the License Setup Wizard dialog box pops up.
    Workaround: Go ahead and select the Add or replace a license file and follow the guided tour. Accept the settings presented in each step to complete the license setup. Another workaround is to allow users write permissions on C:\Program Files (x86)\Agilent\EEsof_License_Tools directory.
  • If SystemVue does not start after you reboot your 64-bit Windows computer, and a license denial message is displayed, then it might be caused by a spurious registry entry. Check to see if registry entry HKEY_LOCAL_MACHINE\SOFTWARE\FLEXlm License Manager\EEsof EDA License Server exists; if it does, remove it and restart SystemVue.

Operating System Roadmap

SystemVue future releases post 2013.08 will not support Windows XP. For more details, refer to /Supported+Platforms">Supported Platforms.
