Genesys 2020 Release Notes


Release Highlights: Dataset Viewer

The Dataset Viewer has been completely revamped with features to explore and organize your data.  Arrays can be transposed; complex multidimensional arrays can be sliced, to winnow out the data of interest; statistics are automatically calculated so that the min, max, mean, etc. is visible at a glance.  Variables are organized into folders on a tree and name filtering is available, so that large numbers of variables don't become overwhelming.  The tree icons indicate whether an item is a scalar, vector, or array and data types are indicated by color: blue for floating point, amber for integer, and green for complex values.  There are viewing options to customize the data display.  The original "Legacy Dataset Viewer" is still available and can be enabled in Tools > Options > General page.



Release Highlights: Parameter Synchronization Tool

The Parameter Synchronization Tool enables easy comparison and synchronization of matching model or design parameters.  Both part and design parameters can be synchronized.  Either (1) select one or more parts on a schematic, right-click, and select "Sync Part Parameters..." or (2) select one or more designs in the workspace tree, right-click, and select "Sync Design Parameters...".


Release Highlights: System Analysis / Models

  • Nonlinear parameters such as P1dB, Psat, and intercept points for non-linear models (amplifiers, nonlinear block, and mixers) now support input impedance corrections. 
    What this means is that you can now enter the measured impedance of their device along with the mentioned nonlinear parameters from the datasheet and internally in the simulator, the non-linear parameters will be corrected for the mismatch to provide the expected results for the given non-linear parameters. 
    This addresses an issue when the PortParamType parameter was changed on non-linear devices to use an impedance other than the reference impedance, which resulted in the actual compression, saturation, and intercepts points to be incorrect.
  • Added four new intercept point measurements (OIP3_OneToneOIP2_OneToneIIP3_OneTone, and IIP2_OneTone) which simulate the 2nd and 3rd order intercept points based on a single tone.
    Intermod measurements for Quick Sweeps are improved to use the single tone intercept points that support both 2nd and 3rd orders. Using these measurements also increased measurement accuracy and speed. It is also simpler to use because a 2nd tone does not need to be configured. See examples RF Amp One Tone Intercept Points.wsv and RF Amp Intercept Quick Sweep.wsv.

    The OIP3_OneTone and IIP3_OneTone measurements do not work with X parameters because harmonic balance simulations, needed for X parameters, do not support signals underneath signals and would be considered a colliding tone.



  • The RF_AMP model can now generate higher-order (>3) harmonics and intermods up to 11th order (see examples RF Amp 11th Order Intermods.wsv and RF Amp Intercept Quick Sweep.wsv). The same algorithm used to generate data flow coefficients for 5th, 7th, 9th, and 11th order from PSat, IP3, and P1dB is used in the Spectrasys RF amplifier. Even order intercept points are estimated using measured data of several typical RF amplifiers.

Release Highlights: RF Libraries

  • The Analog Devices RF parts library has been updated
  • The Custom MMIC RF parts library has been updated
  • The Modelithics SELECT library has been updated
  • The X-Microwave library has been updated. The old X-Microwave library is now obsolete but has has been left in the product to allow workspaces created with prior versions to be loaded and simulated. Several changes have been made to the X-Microwave library. They are listed as follows:
    • All parts are now in a single library. There are no longer individual libraries for each X-Microwave component vendor.
    • The default symbol is now the system behavioral symbol.
    • Each part now has a SymbolMode parameter which defaults to the system behavioral symbol. The user can change this to Hybrid where a physical representation that corresponds to the purchasable X-Microwave block. This can be extremely valuable as the final schematic will very closely represent the X-Microwave hardware. NOTE: The schematic connectivity may break and the respective symbol pins may be in different locations that may also require schematic rewiring. The most effective way to use these parts is to change the symbol, if so desired, before wiring the part. There are also some issues generally with 3 terminal devices and symbol rotation where the symbol does not line up properly with the connecting pins on the symbol.
    • NOTE: Switches in the shipping version of the X-Microwave library will not simulate. This will be addressed by a library update provided by the vendor.

Release Highlights: General Improvements

  • Updated Momentum, the 3D Viewer, and Testlink to their latest versions.
  • Improved the sweep simulation output log to capture information from all simulations run during the sweep. Both distributed and non-distributed simulation logs have been improved.

Release Highlights: Optimization

  • Fixed an issue in Grid Optimization where variable vectors that were shorter than the maximum variable vector size were padded with zeros. The optimization could incorrectly use those zeroes.
  • Updated the Grid Optimization to not require that the length of all discrete vector variables were the same size. This will greatly improve the optimization performance with varying length variable vectors.

Documentation


Starting with the 2020 release, the online help gets a new user interface. The new UI improves overall online help usability by providing the following key benefits in addition to several other minor benefits:

  • Table of Contents Sidebar: Displays collapsible Table of Contents for the entire documentation. The left-double-arrow icon collapses the sidebar, and the right-double-arrow icon displays the sidebar back again.
  • PDF Button: Allows you to instantly generate PDFs of the latest documentation anytime, including current page’s children pages. Currently, the PDF generation option is available only for ADS 2020 release. For other releases, you can switch to their Printing Manuals page and download the existing PDFs like earlier. Note that with the introduction of PDF generation feature, the Printing Manuals page will not be available from next release onward.
  • Product Release Switcher: Allows you to view the current page in other supported releases listed in the drop-down menu. Once you select a release from the drop-down menu, the current page is updated to show the content applicable to the selected release. The Table of Contents is updated as well. With this, you bookmark URL of only one release and then switch to other releases from this drop-down menu.
  • Latest Documentation: The documentation available in the new UI is always kept updated for all supported releases. These updates are available to you as soon as they happen at our end. This provides you 24x7 access to the most recent and technically accurate documentation.

For more details, see How to Use Online Help.


Fixed Issues

System Analysis / Models

  • Fixed issue where an undesired signal at the same frequency as the desired signal would disappear when the signals passed through a mixer and the undesired signal would not be included in the UDCP measurement.
  • Fixed issue with interpolation of S-parameter data resulting in incorrect results.
  • Fixed issue where for a wideband input signal placing a filter before or after a linear amplifier resulted in 3 dB difference in output signal level.
  • Fixed issue with NonLin model using RevIM parameter incorrectly.
  • Fixed some phase noise coherency issues associated with split paths, mixers, then combined back together when the phase noise was only on the input signals.
  • Fixed an issue were the Modulated RF LTE Downlink simulations were broken for ETM12, ETM2, ETM32, and ETM33.

Platform

  • Fixed issue with workspace variables set using VB scripts not retaining their values after workspace is saved and reloaded.

Changes to Existing Behavior

System Analysis

  • Removed Volterra option from System Analysis (Calculate tab). 
  • The default stage value for intercept, compression, and saturation points was increased from +100 dBm to +200 dBm to support Passive Intermod (PIM) simulation and analysis.

Obsolete Items

  • EMPower is no longer supported. User's cannot add a new EMPower analysis but the simulation engine is available internally to run older workspaces.
  • In Advance Part Properties the Simulation Tab was removed. On this tab users were able to override a part with S parameters or a datafile. This technique had some issues and has been replaced, for many years now, using the Model property on the Part Properties dialog box. Users can just change the model to the one they want instead of using the older Simulation Tab method. 

Known Issues 

  • The Modelithics SELECT library part: AMPXP_QOR_RF2878_001_S works correctly using Linear and Harmonic Balance. However, there are errors when using this part in a System Analysis.
  • The Momentum Mesher returns warnings for vias. This message can be ignored as the accuracy of the simulation is not degraded. 
  • Genesys 2018 and later versions are not recognized by ADS 2016.01 or earlier versions of ADS when Using the ADS Link. You need to install ADS 2017 or later versions in order to use the ADS link.
  • If you encounter an error indicating "MATLAB Script engine failed to run" during Genesys start up, make sure the installed version of Microsoft Visual C++ 2005 Redistributable (x64) is 8.0.61000 or higher. You can download and install the latest Microsoft Visual C++ 2005 Redistributable (x64) from Microsoft Visual C++ 2005 Redistributable Package (x64). Note: Please contact Microsoft, if the link does not work.
  • Some issues with plot legends not always being created properly have been observed with MATLAB R2017b under some rare conditions so MATLAB R2018a is recommended when using MATLAB Script in Retail MATLAB mode.
  • MATLAB R2018a is unsupported in Genesys if the current Windows user name contains non-ASCII characters. Use an earlier version of MATLAB, or an ASCII-only user name. Contact support for other possible workarounds.
  • Issue: 3D visualization does not work properly when McAfee antivirus is installed.

    Workaround: You need to disable the McAfee antivirus to make the 3D visualization work.

  • Some dialogs may not render properly on Windows 7 machines using 150% scaling.
      

 

Licensing and Installation

 

Licensing

 


  • Genesys requires: a) the version 2019.02 of the EEsof EDA licensing software, b) a minimum code-word version 2019.02 or above, and c) the licensing server software, lmgrd and agileesofd, to be upgraded to at least the same versions as what are included in EEsof EDA Licensing software 2019.02  Genesys will not start if any of these requirements is not met. Refer to the License Codeword Version Compatibility Table.
  • In the EEsof EDA License Tools version 2019.02, licensing vendor daemon (agileesofd) is integrated with FlexNet FNP 11.13.1.4 version (Windows) and FlexNet FNP 11.13.1.3 version (Linux) of FlexNet license manager daemon (lmgrd). For the Windows platform, Genesys installer will automatically set up these two new license server daemons by default for the local node-locked license users; for the Linux platform, you need to follow the Setting Up Licenses on Linux instruction to complete the licensing configuration process. For more details, refer to Licensing (For Administrators).



  •  Genesys does not automatically release licenses after checking out. From Genesys 2014.03 onwards, Action > Release All Simulation Licenses option is available to manually release all checked out simulation licenses.

Known Issues

 


  • Unable to install Licensing Hardware Key Drivers on Windows.
    Workaround: Turn off UEFI Secure Boot (BIOS) and use the default 6.3 version of the Wibu key driver delivered with the EEsof Licensing tools.

  • Licensing may not support a license file path that is too long. This will likely occur when you have too many license files.
    Workaround: Remove some license files, move the license files to a shorter directory path or to combine license files into a single file.

  • License Setup wizard may not be able to start license server with many license files. During setup, it may lead to a situation where a command prompt window appears/disappears incessantly. This is due to the fact that License Setup wizard is not able to start lmgrd with a long command line and may get stuck in a loop.
    Workaround: 

    1. It is recommended to combine all license code words tied to same MAC ID into single license file to avoid setting large number of license files.
    2. Try to use a shorter path to place license files.
    3. If #1 and/or #2 does not help, start the license server (lmgrd.exe) from the command line (e.g. lmgrd.exe -c <lic-file-path> -l <license_server_log.txt>) and then set <PRODUCT>_LICENSE_FILE=<PORT-NUMBER>@localhost for product you want to use on same PC.
  • Dongle drivers for Flex-10 dongles on Linux are release specific. Installing the latest dongle drivers on Linux will function properly only for the most recent EEsof releases.
    Workaround
    : Install and use dongle drivers as needed.  If you need to run the most recent EEsof releases, use the latest  Flex-10 dongle driver. If you need to use older releases, uninstall the latest dongle driver and re-install the older dongle driver

  • FLO and EEsof License setup are writing server logs at different locations. However, the EEsof server log file location is updated in the License Manager > Environment tab.
  • When multiple same-named INCREMENT lines of different version exist on the license server, few advanced FlexNet options to reserve/limit licenses may not work properly. 
  • Product Selector “Check Availability“ generates incorrect results (which leads to license failure) for older releases when multiple date base versions of like-named bundles exist in the license pool.
  • In Linux, Product Selector OK and Cancel Buttons locations are reserved.
  • Starting from FlexNet Publisher 2015 (also known as version 11.13.1), the adoption of the best practice of the least-privilege security therein results in the License Server related Windows Service to run with the LocalService Account privilege (instead of the LocalSystem privilege as before.)  Running with the LocalService Account privilege, an executable can no longer access any files located in the per-user specific type of folders.  As a result, any license file placed in those folders can no longer be accessed by the License Server when the License Server is automatically started via the Windows Service upon each PC reboot. For the local node-locked license, this would not result in any disruption to the usage of EEsof applications; however, for the license installed on a network PC that is accessed by multiple client PCs, this may cause EEsof applications not to start after the network PC reboots
    Workaround: Store your license files in the Windows folders that are accessible by the LocalService Account privilege.  For example, C:\ProgramData or C:\users\public are both qualified choices.  In general, any folder that has the "Users" group listed in its Properties > Security page and this "Users" group has the read permission enabled should work. 
  • Using the default port to connect to a license server may cause a delay when checking out licenses. If no port is given in the license file, Flexera scans ports 27000 to 27009 to find the port. Starting from FlexNet Publisher 2015 (aka version 11.13.1), the default timeout for the response from each port increased from .1 seconds to 3 seconds.

    To avoid the delay, KSM now issues licenses with port 27009 instead of leaving this blank. The EEsof License Setup Wizard (from Licensing 2017.01 onwards) handles some common situations such as: where it detects license file(s) without port, when users get a new license file with port 27009, or when all license files for a vendor daemon does not have same port.

    You will not be able to start the license server if all license files for a vendor daemon on a server does not have same port.


    Users who manually setup a license server or using EEsof License Setup Wizard with older licensing bits may need to manually edit license files to comply with the following rules:


    1. All license files for a vendor daemon on a server must use the same port (or all be blank). 

    2. Using the default port (blank) is allowed but may result in longer checkout times. 

    3. If setting up a network server, select an unused port that is not blocked by a firewall.

    Workaround: If the user cannot change the port, or wants to use the default Flexera ports, the environment variable FLEXLM_TIMEOUT can be set to .2 seconds (200000), to minimize the performance degradation. However, if the network latency is an issue in your environment, you may need to fine-tune this setting to minimize the general performance degradation while still accommodating the network latency.

  • Installation of EESof EDA tools (such as, SystemVue 2016.08, Genesys 2017.XX, or ADS 2017.XX) may hang at 4% (percentage vary based on the products) for few hours or even more on some specific machines.
    Workarounds:
    • Disable Firewall setting in Anti-Virus Software installed on the PC.
      or
    • Download and unzip process explorer from the below link and then invoke procexp.exe.
      https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx
      Right click on the wusa.exe process under <Product installer exe> and select KillProcess. Now it will continue the product installation.
  • After installing EESof EDA tools (such as, SystemVue 2016.08, Genesys 2017.XX, or ADS 2017.XX) successfully and try to invoke the software or License wizard, you may encounter “api-ms-win-crt-runtime-l1-1-0.dll” missing error.

    Workaround: Install the Update for Universal C Runtime in Windows .  On Windows 64-bit system systems, the file to install is x64 version of the Microsoft hotfix KB2999226. A copy of the Windows6.1-KB2999226-x64.msu Microsoft 64-bit hotfix installer can be found under the C:\Program Files\Keysight\EEsof_License_Tools\bin directory.  The Microsoft hotfix KB2999226 can be found under the Update for Universal C Runtime in Windows  page at  https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows as well.
  • On a newly formatted RHEL system, the EEsof Licensing tools may fail to boot. This is because the FlexNet Publisher 2015 requires a certain rpm
    Workaround: Under the EEsof product installation directory, there exists a utility script named "Linux_sys_check.sh" under the bin directory. Run this script to find out whether any rpm is missing; run this script with a "-y" command-line option to also have all the missing rpms automatically installed if you have the sudo or root privilege.
  • License server may stop recognizing Flex-10 dongle on some systems within a few hours after starting
    Workaround: If you experience this problem, install the latest WibuKey drivers from Wibu Systems.
  • Unable to install Flex-10 driver if Flex-9 dongle is already plugged into a machine
    Workaround: Before installing a Flex-10 driver for the first time, unplug the Flex-9 dongle.
  • There is a known FlexNet Publisher 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.
  • If a user simultaneously runs two instances of a product and has mixed different versions of the same codeword on one license server, extra licenses may be pulled and result in unexpected “Licensed number of users already reached for this feature” errors.
    Workaround: We recommend you 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.
  • 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 and floating bundle operating on Linux cannot be shared between products using EDA License Tools version older than 2014.01 when run at the same time.
  • License Setup Wizard does not remove any previous user-configured FLEX Windows License Service manually set up by a user 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.



      If you have installed an EEsof product released before 1st August, 2014 on your system prior to installing an EEsof product released after 1st August, 2014 then the default EEsof Licensing tools path will remain C:\Program Files\Agilent\EEsof_License_Tools. On the systems that only have EEsof products released after 1st August, 2014 installed then the default EEsof Licensing tools path will be C:\Program Files\Keysight\EEsof_License_Tools.



    • 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 Genesys releases together, set GENESYS_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).
  • For LSF style distributed simulations, ensure that the PATH on the client computer points to the $HPEESOF_DIR/EEsof_License_Tools/${architecture} directory that corresponds to the EEsof release being used. This needs to be done in order to ensure that the proper version of the Flexera utilities (like lmutil ) gets picked up in the path before any older in-compatible 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 if you already have an environment variable set for GENESYS_LICENSE_FILE.
    Workaround: You can use GENESYS_LICENSE_FILE variable to point to license file or refer to Licensing (For Administrators).
  • The License Setup Wizard will exit or not properly configure a license server, if the server has all of its licenses currently in use.
    Workaround: Wait for a license on the server to become available as you normally would before launching the product.
  • Unable to set license in case unicode characters are used either in path or license file name because the Flex License Service does not support these characters.
  • The Product Selector tool will be unable to display the license server status properly when connected to older license server.
    Workaround: Upgrade your license server to the latest version.

  • EEsof Licensing Tools installer can hang on systems with McAfee LiveSafe installed and running the default firewall settings.
    Workaround:  Prior to installing EEsof Licensing Tools, temporarily turn off the McAfee LiveSafe firewall.

  • Licensing setup steps on systems with McAfee LiveSafe installed can fail.
    Workaround:  Under the McAfee LiveSafe firewall settings, under Port and Settings, allow the use of port 27001 for lmgrd.exe under the EEsof Licensing Tools installation bin directory.  Under Internet Connections for Programs , enable lmgrd.exe, aglmmgr.exe and aglmwizard.exe for all devices and turn off monitoring.

  • On Windows, EEsof product releases prior to 2014 can have boot time issues with licensing if an newer EEsof product is installed prior to installing the older product. For example, if a users installs Advanced Design System 2017 and then installs Advanced Design systems 2014.01, the user can have boot time errors with ADS 2014.01.
    Workaround:  For Advanced Design System users,  set a system environmental variable named ADS_LICENSE_FILE under the Control Panel/ System, and Security / System / Advanced system settings and under the "environmental variables".  Add an System variable named ADS_LICENESE_FILE and the value will be the path to your local license file or the port@host setting for your site.

Fixed Issues

  • The issue related to the vendor daemon agileesofd could sometimes crash while the License Manager and the Product Selector was running on a remote Windows 8 machine has now been fixed with the newer FlexNET publisher 2015 (also known as version 11.13.1) that is automatically installed by the Genesys installer.
