Description

In the Questa* FPGA Edition simulator and Questa* FPGA Starter Edition simulator version 2024.1, you might see this error or the following error if you are using the MGCLD daemon v11.16.4
“Unable to checkout a license. Make sure your license file environment variable (SALT_LICENSE_SERVER, MGLS_LICENSE_FILE, LM_LICENSE_FILE) is set correctly”
