Starting with the ISE® Design Suite 11.1 release, all products you have purchased or wish to evaluate can be registered, downloaded and installed at one time from the Xilinx Product Registration and Download site. The following help topics provide answers to the most commonly asked questions about product registration and download.
To download a tool, go to Downloads which provides the general download information. From this page, perform the following:
For TAR formatted files, you will need to use software from a third party provider to untar them. Consult your IT department for assistance. 7-ZIP, GNU built-in tools, WinZIP, and WinRar are commonly used tools for decompression and are licensed solely by each respective developer and not Xilinx. Xilinx hereby disclaims any warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, or noninfringement with respect to these suggested software tools.
In addition to managing the product entitlements for your purchased tools and IP, you can also access product entitlements for No Charge or Evaluation products. Full and No Charge licenses have a subscription period of 1 year. Tools evaluation is for 30-days and IP evaluations are for 120 days.
The redemption of a product entitlement results in the web site producing one or more license keys. When installed, the license keys enable the use of the tool and IP that was purchased or is being evaluated. Your product entitlements and resulting licenses are managed in a product entitlement account on the Xilinx web site.
Product entitlement accounts are company, site and administrator specific. All purchases made can be managed in the same product entitlement account. A company site can have multiple accounts managed by different administrators. This is helpful if a site has multiple design teams working on differing projects with different budget pools.
The original customer account administrator is the "Ship To" contact that is identified during the product ordering process. That person will receive an email with instructions on how to download and license each of the products that were purchased. It is important that the customer account administrator follow the link in the email, as it will ensure that he can obtain access to the purchased products.
Note: A customer who is already licensed for a full version of a Xilinx tool product may test-drive other Xilinx Design Tool product editions or IP. These product entitlements are made available in the same product entitlement account. All user types can download products electronically and request a Xilinx Design Tool DVD.
In order to generate a license for your purchased or evaluation product do the following:
The type of product entitlements available are Full (purchased), No Charge, or Evaluation. Full and No Charge licenses have a subscription period of 1 year. A design tool evaluation is for 30 days and IP evaluations are for 120 days.
End User License Agreements (EULAs): Xilinx Design Tools and No Charge IP product EULAs are agreed to during the product installation process. If you license IP products, you must "accept" the terms of the associated IP product EULAs before the license file can be generated. License Generation Confirmation: Upon completion of the license generation process, you will receive a confirmation message providing a summary of your licensing activity. You will also receive a license generation confirmation email. This message contains the license key file that was generated as an attachment. Add firstname.lastname@example.org as a trusted sender in your address book.
If you have generated a license in the Xilinx.com download center and have not yet received it via email, please check your spam or junk folder. The email can be blocked by email filters. You may need to contact your IT department as the emails can be blocked at the server level. You may also add email@example.com to your safe senders list.
The license can also be directly downloaded from the Product Licensing site at any time. Go to the Manage Licenses tab, select the generated license, and select the Download arrow in the bottom left corner.
The process for modifying a license file uses the same input form as when the file was created except that additional product entitlements of the same license type (floating or node-locked) are made available for licensing.
However, there may be special cases where returns/credits are allowed. If you have any questions, please contact your local Distributor or Customer Service Team.
In the event that a return or credit is approved, you must do the following to change a node-locked seat to a floating seat (or vice-versa).
Certificate-based Licenses (.lic files)
1. Delete all licenses that you have generated for this tool in the "manage license" tab of your Xilinx license account.
2. Agree to the electronic affidavit of destruction.
3. Initiate an RMA with the distributor your design tool was purchased through.
4. Once the RMA has been approved, you may purchase the type of license you require.
Note: If the license type on the Create Licenses tab shows "Floating/Node-Locked," This indicates that the purchase or entitlement allows either a floating or node-locked license to be generated for this product. In this case, steps 3 and 4 (RMA and repurchase) are not needed and you may simple carry out steps one and two and then regenerate the desired license type.
1. Using the server command-line license management tool, xlicsrvrmgr, create a return request for each license to be converted. See UG 973: Vivado Design Suite User Guide: Release Notes, Installation and Licensing, for more information on xlicsrvrmgr
2. Initiate an RMA with the distributor your design tool was purchased through.
3. Once the RMA has been approved, you may purchase the type of license you require.
FlexNet Publisher Licensing, also known as FLEX and previously FLEXlm licensing, is a certificate-based, run-time licensing service sold by Flexera Software and used throughout the industry. The certificate is an encrypted "key" which resides in a "license file". Applications automatically try to check-out a license by providing the "key" to the FLEX services. These services reside on a local machine or a network server.
NOTE: License check-in and check-out happen automatically when an application is open and closed; check-in and check-out do not require a specific action on the part of the user.
New customers or customers requiring renewal will purchase an Edition the Xilinx Design Tools. These Edition products will be distinguished by license types, and this will be reflected in the part number you order.
The license type for a LogiCORE IP license is chosen when the license is generated.
Note: In order to use USB FLEX ID Dongle with Windows operating systems, you will need to install the appropriate driver prior to creating a FLEXnet license for use with it.

A LogiCORE IP Core Full (no source) license key allows complete access to the LogiCORE IP Core netlist and enables you to run through the entire design flow, including implementation, simulation, and bitstream generation. A design containing cores for which a full license exists can be programmed into an FPGA for continued use.
NOTE: When a LogiCORE IP Core evaluation license is replaced with a full license, the core has to be regenerated and the design re-implemented. This ensures that the core netlist does not contain the limitations that characterize evaluation cores.
Purchasing a license for a LogiCORE IP Core's Source Code allows you to generate the LogiCORE IP Core netlist and enables you to run through the entire Xilinx design flow including, implementation, simulation, and bitstream generation. A design containing cores for which you have purchased a source code license can be programmed into an FPGA for continued use. In Addition, the source code license also entitles you to access the source code for the core, which may be generated with the core, or provided to you separately. Source code licenses are only available for a few select IP cores.
NOTE: When a LogiCORE IP Core evaluation license key is replaced with the license provided under a source code license, the core has to must be regenerated and the design re-implemented. This ensures that the core netlist does not contain the limitations that characterize evaluation cores.
No, the FLEX license will not work with any version, update, or service packs of the software that was released after the Version Limit has passed.
The date for a software release is based on the official release date set by Xilinx, not when you actually try to install the software. Therefore, you can install and use any product that was released before the end of the Version Limit, even if the Version Limit has already passed.
There are four ways to obtain a license for a free or purchased product entitlement:1. For Vivado tool activation-based floating licenses:
In order for activation-based entitlements to be active on the Xilinx Product Licensing Site, the site’s URL must contain special machine identifiers. For activation-based floating licenses, these identifiers can only be generated by creating a license request through the xlicsrvrmgr command-line tool run on the machine that will act as the floating license server.
If this is the first time xlicsrvrmgr is to be run on a floating license server, then you will need to ensure that the computer's trusted-storage area, where activation authorizations are stored, is first installed and initialized. In the License Management Tools download, you will find an initialization utility that varies by OS. Run the commands as specified below from the directory where the License Management Tools were unzipped:
Windows:installanchorservice.exe xilinxd Xilinx-Design-Suite-Software
Once the trusted storage area is initialized, do the following steps to create a license file request:
2. For all other types of Vivado tools and IP licenses, from the Vivado License Manager (VLM):
- Chose the “Obtain a License” screen.
- Select the desired license type and click either the “Connect Now” button, if you are connected to the internet, or the “Save Information” button to create an HTML file for later use when internet access is available
3. For ISE tools and IP licenses, from the Xilinx License Configuration Manager (XLCM):
4. For certificate based tools and IP licenses, a customer can also go to the Xilinx Product Licensing Web page and enter the required information directly.
The FLEX HostID can be obtained through any of the following means:
The Xilinx FLEX Administrator can be anyone trusted to generate FLEX floating licenses and to grant Admin, Floating License, or End User privileges to other persons for the customer account. The initial Xilinx FLEX Administrator is the person that is identified on the purchase order as the End-user or Administrator contact.
NOTE: A purchasing agent should NOT be listed for this!
The end-user or administrator can initiate a re-host (Modify License) operation from the Xilinx Product Licensing website for certificate-base licenses. In order to modify an existing license file, click on the Manage License tab, select the license file in the master view and then click the Modify License button in the detail view.
After clicking to agree to destroy all copies of this old key, the customer will be able to generate a new key for the new machine. An end-user is allowed 3 of these self-service re-host operations, and an administrator is allowed 5 deletions or re-hosts per major release. If that number is exceeded, the end-user or customer administrator would need to call Xilinx Customer Service to have automated re-hosting/deletion permissions reset.
NOTE: If you are entitled to a site license for a feature you should simply visit the Xilinx Product Licensing website and generate a new license with the HostID of the new computer.
It is a license that is locked to a specific machine or, for certificate based-licenses, a dongle. The license is uncounted, meaning that there can be an unlimited number of simultaneous runs (by any user) on the single machine.
Example Node-Locked License
INCREMENT System_Edition xilinxd 2013.06 permanent uncounted \ EE05B6C46335 \ VENDOR_STRING=joe.smith@acme,System_Edition,software,permanent,_27773986_134688_210178122_805 \ HOSTID=00216a62bb5c ISSUER="Xilinx Inc" START=22-Jul-2012 \ TS_OK
For XLCM: Look in the license table on the Manage Xilinx Licenses tab.
For VLM: Look on the View License Status screen.
Xilinx Software and LogiCORE IP CORE licenses contain the TS_OK string to allow use from a remote desktop.
Certificate-based Network Floating Licenses and activation-based Server Licenses are locked to a license server host running the FLEX license server daemon. A floating license is counted, which means there is a quantity entered in the "count" field of the FLEX license equal to the number of "seats" hosted by that server. A license is checked out per unique user. Therefore, if Joe and Bob are running Vivado implementation on two different machines at the same time, two Vivado seats will be checked out. For example, the license below allows for 10 seats of PlanAhead, ChipscopePro, and/or ISIM to be run simultaneously.
#Example Floating License # SERVER my_server1 80f0e696 2100 # USE_SERVER # VENDOR xilinxd # # This license is valid for permanent ( 0 days ) from Thu Mar 05 16:53:45 GMT+00:00 2012 INCREMENT Logic_Edition xilinxd 2013.03 permanent 10 9AF27E183C6D \ VENDOR_STRINGfirstname.lastname@example.org_Logic_Edition_software_permanent_1000 \ ISSUER="Xilinx Inc" START=05-Mar-2012 TS_OK # --------------------------------------------------------------- # PACKAGE Logic_Edition xilinxd 2013.03 BCA973EE74F2 \ COMPONENTS="PlanAhead ChipscopePro_SIOTK ChipscopePro ISE \ ISIM" OPTIONS=SUITE
When I receive my generated floating license, should / can the license be edited in any way? When generating a certificate-based floating license on the Xilinx Licensing site, you are prompted for the server name and hostID. Additionally, a port number (2100) is added to the generated license.
Yes, in order to generate a 3-redundant server license, for a floating license, the Xilinx license account or floating license administrator will need to select ‘Yes’ on the right of the “Redundant Server?” line. This will enable the administrator to select or add hostID information for a primary and two backup servers. In a Redundant license server system: Three machines are identified as license servers, but only one is the master that can issue licenses. Each machine has an identical copy of the license file with three SERVER lines, one for each SERVER identified.
As an alternative to Redundant License servers, some users prefer to use a license-file list. When using a License file list: Split the licenses into multiple files and identify the locations in the XILINXD_LICENSE_FILE environment variable separated on UNIX by a colon (:) and on Windows by a semicolon (;). Example: 1700@mylicense1: 1700@mylicense2
To create a basic license file:
From a command shell containing a path to the Xilinx server tools run lmutil lmhostid Choose one of the host id's produced by the previous command and create a file, perhaps called "Xilinx_Server.lic", which contains the following text: SERVER 〈host_name〉 〈host_id〉 〈port〉
For port number, Xilinx's default is 2100, although any unique port number may be used. The command to serve the activation licenses in this example, would be:
lmgrd –c Xilinx_Server.lic
For clients to point to a Floating License key either the XILINXD_LICENSE_FILE variable (preferred) or the LM_LICENSE_FILE variable must point to the port@server location.
Note: For Linux operating systems, licensing environment variables cannot be set using the Xilinx License Configuration Manager (XLCM). The environment variable fields are read only, therefore they are grayed out and there are no "Set" buttons. The environment variable must be set using the appropriate shell and commands.
The easiest way to check for all available Xilinx licenses is with the Xilinx License Configuration Manager (XLCM)or the Vivado License Manager (VLM). In XLCM select the Manage Xilinx Licenses tab, or in VLM, select the View License Status screen. The license manager will indicate all Xilinx licenses running on servers pointed to by XILINXD_LICENSE_FILE and LM_LICENSE_FILE environment variables as well as licenses located in the $HOMEDIR/.xilinx directory. Alternately, from a command shell, the "lmutil lmdiag" command can be used to show all FLEX licenses available in a given directory or running on a given server.
lmutil lmdiag -c c:\.xilinx
lmutil lmdiag -c 1700@my_license_server
Xilinx applications (including XLCM and VLM) look for FLEX licenses in the locations and order listed in the following table:
|Order||Windows Location||Linux Location|
|1||Activation-based licenses: Local Trusted Storage Location||Activation-based licenses: Local Trusted Storage Location|

If a license component (e.g. ISE) is available in multiple license packages (e.g. a Logic Edition and a System Edition license), the license that is used is selected in the following order.
Rules 2, 3 and 4 can be overwritten for certificate-based licenses with the use of a "sort" directive. The sort directive can be added to the Increment line without affecting the drc of the increment. The feature or increment with the lowest sort value is used first.
Example: In the license file below, if PAR were run, the ISE component of the Logic_Edition Package would be used first even though the version limit of the System_Edition Increment is older.

XLCM has the following informational fields for each license key found:
A LogiCORE IP Core license is checked:
General LogiCORE IP Core license status can be obtained by opening XLCM or CORE Generator. Detailed information can be obtained by running the following at a command prompt.
Xlicmgr status –c <feature name> -v
No, after you purchase or register for a LogiCORE IP Core license, you will be able to obtain the license from the Xilinx Licensing website: http://license.xilinx.com/getLicense?group=esd_oms&tab=CreateLicense
The following cores are not enabled by FLEX license keys and will continue to be distributed through restricted access IP product lounges until further notice:
|Turbo Product Code Encoder||(DO-DI-TPCENC)|
|Turbo Product Code Decoder||(DO-DI-TPCDEC)|
Prior to the ISE Design Suite 11 release, protected IP lounges were used to restrict access to full license key generation web forms and IP user guides. Starting in 11.1, please use the Product Download and Licensing Site to generate IP license keys. The license generation pages in the product lounges will not be updated to support new IP versions. In addition, most IP user guide documents previously available only in protected lounges will be available to all customers from the public Xilinx Documentation Center.
Search on IP Center for the product page for the core. A core which requires a license key will either have a “Get License” on the main product page (no charge IP) or instructions in the “Evaluate” or “Order” link on the product page that indicate that a license key is required.
Open CORE Generator IP catalog or Project Navigator New Source Wizard, Select IP page and look in the License column. Any LogiCORE IP Core that requires a license key will show a small padlock icon adjacent to it in this column. A ‘$’ on the padlock icon indicates that the license key must be purchased. A padlock icon without a ‘$’ indicates that the license key is available at no additional cost to licensed ISE customers.
In the Vivado IDE open the IP Catalog and look in the License column of the IP catalog. Any LogiCORE IP Core that has the required license included as part of the Xilinx installation will show the word 'included' in this column. Any LogiCORE IP Core that requires the user to purchase and additional license in order to use the IP will show the word 'purchase' in this column.
This is most likely because you have entered the Xilinx Product Licensing site directly, either from a referring link or by typing an address into the internet browser. For the “Activation Based Licenses” section to be active, the Xilinx Product Licensing site must be accessed through either Vivado License Manager (VLM) or either the xlicclientmgr or xlicsrvrmgr command-line utility.
Another common reason is that an Activation license has already been generated using this unique request ID. This can often be caused by attempting to generate another license before the previous response.xml has been processed into the local trusted storage. Please process any previously created response.xml files before attempting to obtain another license.
This is most likely because you have entered the Xilinx Product Licensing site from Vivado License Manager (VLM) or xlicclientmgr. In order to be able to generate activation-based floating licenses, you must enter the Xilinx Product Licensing site by following a URL generated by the xlicsrvrmgr utility run from the machine you intend to use as a floating license server. For more details, see the "How do I obtain a license for a free or purchased product entitlement?" question in the Obtaining a License section of this FAQ.
If you do not see products you purchased in the product table of the Create License page, it is likely that you do not have the proper entitlements set up for your user account. When the order for the Xilinx Design Tools or IP product you purchased was made, a notification was sent to the individual identified as the "Ship To" contact person on your order.
If you are this person, you should have received a Xilinx notification which contains instructions and a unique URL for providing you access to the products you have purchased. If you do not have this e-mail, check to make sure it is not in your spam folder.
If you are not the person identified as the "Ship To" contact person on your order, you will need to find this person and have them log into the site and add you as an "end user" or "customer account administrator" for your account. They will need your e-mail address in order to do this.
If you do not know who the "Ship To" contact person is for your order, please contact Xilinx Software Customer Service.
To correct errors or omissions in your profile information, please reinitiate the sign in process for product registration. You will be prompted with an address validation screen. At this point you can correct any mistakes in your profile and continue with the product registration and download process. Additionally, a notification has been sent to a Xilinx customer service representative who will review the alert and if necessary, will contact you regarding your account status.
These troubles may be related to your system, your ISP and connection to the Internet, or the interaction of your system with the Xilinx Product Download and Licensing Sites. Here are some suggestions that should help:
Xilinx values and safeguards your privacy and security. We provide 40-bit SSL (Secure Sockets Layer) encryption to protect your personal information as it travels across the Internet. SSL protection is provided throughout the Xilinx Product Registration and Download Site. All modern browsers support SSL. If yours does not, we recommend upgrading to a newer version for better privacy protection.
Access to your registration information is available only when your username and password are entered correctly. For your protection, our customer service representatives are not authorized to change your information in any way. To learn more about how Xilinx safeguards your personal information, please read the Xilinx Privacy Statement.
The software on the Xilinx Product Download Site is subject to strict license and export compliance controls, thus various security systems are built into our download site. This security architecture relies on the HTTP protocol for downloads, so we do not provide an FTP option.
Upon completion of the registration process, you will advance to the Download Software screen. Below the green "DOWNLOAD" button in the "Quick Links" section is a link labeled "Request a DVD". Clicking on this link will take you to a DVD request form. In most cases, a DVD can be mailed to you within 3-4 weeks.
DVDs are no longer being produced for ISE 10.1 software and all previous 10.1 DVD inventory has already been shipped.
First, you need to install ISE 10.1. At the end of installation, you will be asked to run XilinxUpdate. If you accept, XilinxUpdate will attempt to connect to the Xilinx website and will prompt you to download the latest available updates to ISE 10.1.
Alternately, you can go to Downloads, and select the Service Pack you wish to download. After unarchiving the install, run the setup executable to launch the updater.
There are currently no plans to make further updates to ISE 10.1. However, if a significant issue is found in the future, a tactical patch will be considered. Go to Technical Support to open a webcase.
Similar to support for ISE® Classics, Xilinx Technical Support continues to support this version if the customer is targeting any of the devices removed in 11.1 and future versions. However, Xilinx Technical support does not support a customer is using 10.1.03 and targeting a device found in ISE DS 11.1.
Go to the Xilinx Licensing Solution Center, under "Need to Generate a Registration ID for Legacy products" question. Select the release you need a registration ID for, and follow the instructions on the subsequent pages.
