Known Issues

Design and Technology Management

  • Using ADS 2020 with pycell studio 2018 (PyCell Studio Packages: Release O-2018.09) might prompt you an OA version mismatch warning message on the linux terminal. However, there is no impact on the iPDK flow in ADS.
    Linux terminal message:
    Requested minor API version '518', which is supported by OpenAccess build '22.50.030' is newer than the minor API version '514' of the shared library of OpenAccess build '22.50.043'.

  • The Express Pcell plugin that comes with Virtuoso IC version 6.1.8 does not work with ADS 2020 due to an OpenAccess version mismatch.
    Workaround: When running ADS 2020, set the LD_LIBRARY_PATH environment variable path to point to the directory from IC version 6.1.7.

  • AEL constants are protected and should not be modified in any DDS expressions.  An AEL error will be issued in case an attempt to modify an AEL constant occurs.

  • Python Datalink
    • When using Connection Expert 2019 connected to Lan Instruments, there may be error messages during dl_visa_query() and dl_visa_write().
    • Exceed on Demand: Note that in some cases, EoD settings may need to be configured to properly display Spyder.  Please contact your EoD support representative for additional guidance.

Design Guide

  • Simulating the "1_Sim_CA" design in the DDR4 CTB design guide prompts the netlist error.
    Workaround: Open the schematic design "PatternGen_CA_Continuous" and arrange the pin numbers in order.
  • Simulating of schematics in the HDMI_Link_Simulation design guide prompt the netlist error.
    Workaround: Open the schematic design “HDMI_Diff_RX” and arrange the pin numbers order in order.

Circuit Simulation

  • General

    • Simulation Manager may not work on Windows and throw exceptions for some designs.

    • ADS 2019 will not be compatible with Verilog-A files, which have been encrypted before ADS 2019. There is no change for non-encrypted Verilog-A files.

    • TMI models are supported for pure Hspice syntax only. The support of hybrid syntax (mixing Hspice and Spectre) is planned for a future release. 
    • BSIMSOI models using TMI modeling is not supported yet. Classical BSIMSOI models are supported as before.
    • TMI Aging simulations are not supported
  • Electrothermal

    • You may not be able to start a Transient/Envelope Electro-Thermal (ETH) simulation only when the same testbench is open in the viewer of Transient/Envelope thermal results. You need to close the viewer before launching a Transient/Envelope ETH simulation.

    • The electrothermal simulation will not run on designs created using Smart Mount for Multi-Technology feature.

    • Paths set while configuring the ETH controller may need to be updated when the workspace is moved across operating systems.

    • On a fresh Linux machine, electrothermal simulation fails with the following error message:

      Heatwave returned an unknown error code 127.

      Workaround: The error could be due to missing packages, for example, libpng12. Verify your system meets the requirements using the linux_sys_check.sh script. For more information,  see Checking Installed RPM Files and the Operating System Version.

    • If you get licensing errors while running thermal simulation, you may need the following workaround.
      Workaround: Rename the file  $HOME/.eesofrc. For example,  $HOME/.eesofrc-orig.

    • Electrothermal does not support remote simulation, batch simulation, Monte Carlo, tuning, Optimization, and Measurement Equations. Also, you cannot sweep directly on the DC controller.

    • All libraries referenced in a layout should use the same layout resolution, namely the OA database units (DBU) per user unit (UU).

    • You cannot run both a transient and envelope simulation on the same design from one testbench.

    • The calculation of power dissipation from passive components other than resistors may not be correct in harmonic balance simulations.

    • Electrothermal does not support the transient or envelope simulation that is controlled by a ParamSweep.  

    • If you get "Maximum timestep reduced to half of shortest transmission line delay " warning, it can lead to transient simulation to not converge   
      Workaround: Unselect "Limit timestep for Transmission Line" option on Time Setup tab of Tran component to get it work.

    • On Linux, if you specify the THERMAL_DIRECTORY variable in eesof_lib.cfg file using backward slash (..\thermal), the thermal simulation does not run properly.
      Workaround: Specify the THERMAL_DIRECTORY variable using forward slash (../thermal) instead of backward slash.

    • The ETH viewer does not support 4K displays. A few instances of text and icons may appear distorted. 

    • You receive an error message in substrate editor that you cannot use the same layer number more than once. You can safely ignore this error during thermal technology export.

    • On a fresh Windows 10 system, Electrothermal simulation terminates with an error. 
      Workaround: Install the following Microsoft Visual C++ runtime components: 

      http://www.microsoft.com/en-in/download/details.aspx?id=30679 
      https://www.microsoft.com/en-in/download/details.aspx?id=5555

  • DDR Design 

    • You receive an error message to check port numbering when performing simulation with SnP component for differential configuration.
      Workaround: Select the first option in Pin Configuration for the SnP component.

HSD Design

  • SerDes
    • You receive an error message when runtime libraries for some of the ADS example ibs files (for old AMI models) are unable to get installed automatically during the ADS install. 
      The error appears eventhough the ibs file is supported on specific platform. 
      Workaround: Microsoft Visual C++ 2010 runtime library is required to run the dll files. Download the following library if it is not installed:

      https://www.microsoft.com/en-us/download/details.aspx?id=14632

  • EM-SI/EM-PI
    • SIPro/PIPro, Via Designer 
      • On Windows 10 with Intel HD graphics, Via Designer may show an error message ‘Failed to use the connection between ADS and Via Designer.’  This has been isolated to the latest release of Intel HD Graphics drivers (23.xx.xx.xxxx).
        Workaround: Downgrading graphics driver to the previous recommended driver resolves this issue (e.g., 22.20.16.4836,A05).
      • DirectX 9 as graphics driver is no longer supported. DirectX 11 is thus be used by default. Run "diagdx" to verify which DirectX version is supported on your system.
    • SIPro/PIPro
      • ADS 2020 is not compatible with the latest available Samsung component models released in June 2018. The support for the component models is planned to be added in an upcoming update release.
      • Simulation failure when using components with S-parameter models or for which the model is defined using a lib/cel/view in case the Updating model does not require new simulation is not set. As a workaround, turn on the option. For PI-AC simulations, the options are turned on by default, for SIPro, this needs to be turned on explicitly.
      • If you run SIPro/PIPro on a fresh machine with Suse 11 installed, you may encounter the critical error, "EMPro exited unexpectedly during execution."
        Workaround: Run the following commands:

        cd $HPEESOF_DIR/fem/2020.00/linux_x86_64/bin
        ./startempro --personality=sipi --driver=x11
        Ignore any license related error messages that may show up on executing these commands. These driver settings are saved for future sessions.
    • PIPro-DC
      • The power graph is not correct when VRM's or Sinks are defined starting from pin definitions. All the other result data is correct. This issue does not occur when VRMs and sinks are defined from component instances.

EM Simulation

  • RFPro
    • The FEM Generation 2 in this release gives a preview on new technology that is still under development. In case it does not handle your design, switch back to Generation 1.
    • Project load fails with the error 'OccDesign::getNet: key not found' when a layout shape has a multi-bit net name (e.g. 'd<7:0>' or 'a,c,net1').
    • With McAfee Endpoint Security (ENS) enabled, the Momentum surface current visualization hangs.
      Workaround: Disable the "Enable Adaptive Threat Protection" flag in McAfee ENS.
    • DirectX 9 as a graphics driver is no longer supported. DirectX 11 is thus used by default. Run "dxdiag" to verify which DirectX version is supported on your system.
    • If you run RFPro on a fresh machine with Suse 11 installed, you may encounter the critical error, "EMPro exited unexpectedly during execution."
      Workaround: Run the following commands:

      cd $HPEESOF_DIR/fem/2020.00/linux_x86_64/bin
      ./startempro --personality=rfpro --driver=x11
      Ignore any license related error messages that may show up on executing these commands. These driver settings are saved for future sessions.
  • EM Setup
    • On a Virtual Windows 10 system with Microsoft Hyper-V Video display driver, the 3D EM Preview with EM Setup Preprocessing may bring up a dialog with a Hoops error, and, after suppressing the dialog, it opens up blank.
  • Distributed simulations
    • The example implementation of the sitecluster command for LSF clusters may lead to failing simulations if the path or number of threads is too large.
      Workaround: See the workaround details in the sitecluster documentation.

Power Electronics

  • PowerMOS_SiC power devices operate under a very wide range of voltage and current slew rates and it is a challenge to create a model that converges under all conditions – especially conditions that depend upon what components are connected externally to the power device in the circuit schematic. Please contact technical support if you encounter such an issue when attempting to use this model.

  • If you run PEPro on a new machine with Suse 11 operating system, you may encounter the critical error, "EMPro exited unexpectedly during execution."
    Workaround: Run the following commands:

    cd $HPEESOF_DIR/fem/2020.00/linux_x86_64/bin
    ./startempro --personality=pepro --driver=x11

    You can ignore any license related error messages. These settings are saved for future sessions.

Installation

  • While installing a new version of ADS, if you see “Previous version detected” error even after you have already run the uninstaller for that version of ADS, you may need to manually uninstall ADS before installation of the new ADS. To manually uninstall ADS, perform the following steps.
    1. Exit the current ADS installation session if it is running
    2. Remove or rename the file .com.zerog.registry.xml  under the folder  C:\Program Files\Zero G Registry . Both the folder and the file are by default hidden, so you may need to change the folder viewing setting to show hidden files and folders, do so via the Advanced settings of the View tab in the Windows Folder Options dialog box.
    3. Remove the ADS installation directory through the Windows Explorer.
  • After performing the above steps, you can re-start the ADS installer.

  Back to Feature Updates

Licensing

  • 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 ADS releases together, set ADS_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 ADS_LICENSE_FILE.
    Workaround: You can use  ADS_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.
