Vivado is a software tool developed by Xilinx for designing, synthesizing, and implementing FPGA and ASIC systems. Vivado supports various Xilinx devices, such as Zynq, UltraScale, and Versal. To use Vivado, you need to obtain and install a license that matches your product edition and device family.
There are two types of Vivado licenses: node-locked and floating. A node-locked license is tied to a specific machine or host ID, and can only be used on that machine. A floating license is stored on a license server, and can be shared by multiple users on different machines, as long as the number of concurrent users does not exceed the number of licenses available on the server.
There are also different levels of Vivado licenses: WebPACK, Design Edition, System Edition, and HLS. WebPACK is a free license that supports a limited set of devices and features. Design Edition is a paid license that supports all devices and features except for system-level design tools. System Edition is a paid license that supports all devices and features, including system-level design tools such as System Generator and Model Composer. HLS is a paid license that supports high-level synthesis for C/C++ and SystemC code.
To obtain a Vivado license, you need to have an account on the Xilinx website. If you do not have an account, you can create one for free. Once you have an account, you can access the Xilinx Product Licensing Site to manage your licenses.
If you want to obtain a free WebPACK license, you can follow these steps:
If you want to obtain a paid Design Edition, System Edition, or HLS license, you can follow these steps:
To install a Vivado license, you need to load it in XCLM using one of these options:
Once you load your license file in XCLM, you can view your license status by clicking on the "View License Status" option. You can see the details of your license, such as product name, version, expiration date, device support, and feature support. You can also see if your license is node-locked or floating, and if it is in use or available.
If you have multiple licenses, you can prioritize them by clicking on the "Prioritize Licenses" option. You can drag and drop the licenses to change their order. The license at the top of the list will be used first by Vivado.
In this article, we have learned how to get and install a Vivado license. We have also learned about the different types of Vivado licenses and how to manage them in XCLM. We hope this article has been helpful for you to start using Vivado for your FPGA and ASIC design projects.

Sometimes, you may encounter some issues with your Vivado license, such as license expiration, license mismatch, license corruption, or license server failure. In this section, we will provide some tips on how to troubleshoot and resolve these common issues.
If your Vivado license has expired, you will see a warning message in XCLM or Vivado, indicating that your license is no longer valid. To renew your license, you need to contact Xilinx or your distributor and purchase a new license. You can then obtain and install the new license file as described in the previous sections.
If you have a WebPACK license, you can renew it for free by following these steps:
If your Vivado license does not match your product edition or device family, you will see an error message in XCLM or Vivado, indicating that your license is not compatible with your design. To resolve this issue, you need to obtain and install a license that matches your product edition and device family. You can purchase a new license from the Xilinx Online Store or an authorized distributor, or upgrade your existing license by contacting Xilinx or your distributor.
If your Vivado license file is corrupted or modified, you will see an error message in XCLM or Vivado, indicating that your license is invalid or tampered. To resolve this issue, you need to obtain and install a new license file from the original source. You can download the original license file from the Xilinx Product Licensing Site if you have an online account, or contact Xilinx or your distributor if you have an offline account.
If your Vivado license is stored on a license server, you need to make sure that the server is running and accessible from your machine. If the server is down or unreachable, you will see an error message in XCLM or Vivado, indicating that your license is not available or cannot be checked out. To resolve this issue, you need to check the status of the server and fix any network or configuration problems that may prevent the communication between the server and your machine. You can also try to restart the server or use a different server if possible.

Sometimes, you may want to change your Vivado license settings, such as switching between different licenses, changing the license server address, or setting the license environment variables. In this section, we will provide some tips on how to change your Vivado license settings using XCLM or Vivado.
If you have multiple licenses for Vivado, you can switch between them by using the "Prioritize Licenses" option in XCLM. You can drag and drop the licenses to change their order. The license at the top of the list will be used first by Vivado.
You can also switch between licenses by using the "Manage License Search Order" option in Vivado. You can access this option from the Help menu or the Tools menu. You can add, remove, or reorder the licenses in the search order list. The license at the top of the list will be used first by Vivado.
If you have a floating license for Vivado, you need to specify the license server address in your license settings. You can do this by using the "Set Xilinx License Server Address" option in XCLM. You can access this option from the Edit menu or the Tools menu. You can enter the server name or IP address, and optionally the port number, in the text box. You can also use a comma-separated list of server addresses if you have multiple servers.
You can also change the license server address by using the "Manage Xilinx Licenses" option in Vivado. You can access this option from the Help menu or the Tools menu. You can select the "Use a network license server" option and enter the server name or IP address, and optionally the port number, in the text box. You can also use a comma-separated list of server addresses if you have multiple servers.
If you want to use environment variables to control your Vivado license settings, you can do this by setting the following variables:
You can set these variables in your system settings or in your command-line shell before launching Vivado. For example, on Windows, you can use these commands:
set XILINXD_LICENSE_FILE=C:\Xilinx\license\mylicense.lic
set XILINX_USER_LICENSE_FILE=\\server\license\sharedlicense.lic
set XILINX_PREFER_LICENSE=System_Edition
On Linux or Mac OS, you can use these commands:
export XILINXD_LICENSE_FILE=/home/user/Xilinx/license/mylicense.lic
export XILINX_USER_LICENSE_FILE=/mnt/server/license/sharedlicense.lic
export XILINX_PREFER_LICENSE=System_Edition
