Set Up Questa-Intel FPGA Edition License for GeMRTOS Nios V

The Questa-Intel FPGA Edition software is the simulation tool required for verifying GeMRTOS designs on Altera FPGA platforms with Nios V processors. Before launching Questa, the license must be configured using the Siemens EDA license daemon mgcld and the MGLS_LICENSE_FILE environment variable. This guide covers both supported license configuration methods: a local license file and a network license server.

License Setup Requirements #

The Questa-Intel FPGA Edition software uses the Siemens EDA license daemon mgcld to manage license access. On Windows, the mgcld daemon is located in the Questa-Intel FPGA Edition system directory:

  • Windows: <Questa - Intel FPGA Edition system directory>\

The license daemon must be running and accessible before Questa can start. You can use either a local license file or a floating license server.

How to Configure the License #

Before starting the Questa-Intel FPGA Edition software, set the MGLS_LICENSE_FILE environment variable to point to the license. Two formats are supported:

  1. Local license file: set MGLS_LICENSE_FILE to the full path of the license file:

    MGLS_LICENSE_FILE (<Questa installation directory>/licenses/eda/license.dat)

  2. License server: set MGLS_LICENSE_FILE to the port and hostname of the license server:

    MGLS_LICENSE_FILE <port>@<hostname>

Key Takeaways #

  • Questa-Intel FPGA Edition requires the mgcld Siemens EDA license daemon — on Windows it is located in the Questa system directory.
  • Set the MGLS_LICENSE_FILE environment variable before launching Questa; it accepts either a local file path or a <port>@<hostname> license server address.
  • This configuration must be completed before running GeMRTOS Nios V simulations in the Quartus Prime / Platform Designer design flow.
