Questa Starter Edition 25.1 - svverification license checkout fails (valid license per lmdiag)
Hi, I'm running Questa*-Altera FPGA Starter Edition 25.1std on Windows 10.
My design compiles and elaborates successfully, but simulation fails when
loading a testbench that uses SystemVerilog classes, randomize(), and
covergroup:
** Error: Failure to checkout svverification license feature.
** Error: (vsim-1) Unable to checkout verification license - required for
testbench features (randomize, randcase, randsequence, covergroup).
License details:
- License: SW-QUESTA (Non-Commercial Software SW-QUESTA), FIXED, NIC ID
- Feature: intelqsimstarter, v2027.01
- Node-locked correctly to my machine's NIC ID (confirmed via lmutil lmdiag)
- License Expires: 26-Jul-2027, currently active and valid
lmutil lmdiag output confirms the license is valid and correctly bound:
"intelqsimstarter" v2027.01, vendor: mgcld, expiry: 26-jul-2027
uncounted nodelocked license, locked to ethernet address "d053493e9348"
starts: 26-jul-2026, expires: 26-jul-2027
This is the correct node for this node-locked license
Both LM_LICENSE_FILE and SALT_LICENSE_SERVER are correctly set to the
license file path (verified spelling, no typos, no spaces in path, full
system restart performed). The GUI itself launches without any license
error - the failure only occurs specifically when loading a design that
uses randomize/covergroup.
Is svverification/testbench verification simply not included under the
free Starter Edition license (intelqsimstarter), or is there an additional
configuration step needed to enable it? Any guidance appreciated.
Yes, you are right that the Questa Altera FPGA Edition does not support advanced verification features. Please refer to the Knowledge Base article below for details:

Any SV verification constructs (randomize, randcase, randsequence, covergroup) require you to use Siemens EDA QuestaSim*. (non-FPGA edition)
