Licensing

Overview

The Tanner Suite and additional software is licensed via the Mentor Graphics licensing system (MGLS). There are two types of licenses, namely:

  • Networked (Floating) Licenses
    • This license is widely used, both because the convenience of sharing licenses through the local network as well as enabling flow tools such as Calibre One and Tanner P&R.
  • Node-locked (Mobile Compute) Licenses
    • A node-locked license is popular if you will only be using tools in one environment, but is constrained to a hardware lock of your choice (portable USB dongle or any local (non-networked) MAC-address).

The main difference between them is that the floating licenses can be shared from a license server across several devices, whereas the Node-locked licenses can only be used with the node-locked device.

Requirements

Before you proceed with installing the licensing, you will need the following:

  • "Mentor Install" Software installed (This is bundled with every product release), and can be found under Start Menu > Mentor Graphics > Mentor Install
    • If this is not installed, run any Mentor Product Windows installer (.exe) to install it.

AND

  • A license server machine already set up on your local network   

OR

  • A Tanner License file (.txt) tied to an accessible MAC-address on your computer, connected hardware lock (USB Dongle) OR on your network (Network Licenses only)

How do I setup Network Licensing?

Setting up the license server machine:

  1. Run Mentor Install, go to "Manage Licensing" and "Install Licensing Software", and complete this installation
  2. Locate the Tanner License File you were sent, and open it with your favourite text-editor to make the following changes:
    IMPORTANT: Be careful not to edit anything in this file but these fields:
    • put_server_name_here
      • Replace with portname@hostname,
        eg 1717@PC_name or 1717@<license_server_ip_address>
    • path_to_mgcld
      • Replace with the full path to mgcld.exe, by default C:\MentorGraphics\Licensing\ mgcld.exe
  3. Save the file and exit the text-editor
  4. In Mentor Install, navigate to "Configure Licensing" and "Import License File", then select the license file you edited. Follow the dialogue box until finished
  5. Your service should now be up and running. You can verify and alter settings in by running LMTOOLS.exe (Start Menu > Mentor Graphics Licensing > lmtools or 'Licensing' folder)

Setting up the client machine:

Setting up networked licensing on a client machine requires that the license server machine is setup with the license server running with your license file.

  1. Run Mentor Install, go to "Manage Licensing" and "Install Licensing Software", and complete this installation
  2. Go to "Configure Licensing", and choose "Point to a license server"
  3. Enter the server machine's portname@hostname.
    Example: 1717@johndoe-pc  or 1717@<clientpc_ip_address>
  4. Click "Test" to ensure correct setup – A dialogue box will confirm
  5. Click Next and Done, and the licensing server should have been set up

Your Tanner software should now be able to license and run.

How do I install a single node-locked licence?

To install a node-locked license:

  1. Run Mentor Install, go to "Manage Licensing" and "Install Licensing Software", and complete this installation.
  2. Attach the Hardware lock to your PC
  3. Next, go to "Install Hardware Key Drivers", select your hardware key and press Install
  4. In Mentor Install, navigate to "Configure Licensing" and "Import License File", then select the license you received. Follow the dialogue box until finished.

Your Tanner software should now be able to license and run.

Common Issues

  • Some issues may occur during the setup of floating licenses due to firewall settings. Please ensure that MGCLD.exe (found under your 'Licensing' folder), and other licensing executables are enabled through the firewall
  • Ensure there is a stable connection between your client and server machines. You can run the "PING <IP-Address>" command from the Command Prompt to ensure both machines are able to communicate properly
  • When using Node Locked licensing, ensure that the USB Key is identified by your system. This can be verified from the Device Manager in Windows. The key will be listed as a SafeNet key device under "Universal Serial Bus controllers". If the device is unidentified, then please try the following:
    • Remove the USB key and reinstall the key drivers from the Mentor Installer
    • Select the Install tab, then "Install Hardware Key Drivers"
    • Follow the instructions and restart your PC. Then please check again
    • If this problem persists, try attaching the USB Hardware Key to a different USB port.
