Are you upgrading?
From 5.6x or an earlier version
When you upgrade to 5.7, you’ll need to regenerate your design libraries
after installing the software. See "Regenerating your design libraries" (p24)
for details.
From 5.2 or an earlier version
Since version 5.3, ModelSim has used version 6.1g of FLEXlm (all
FLEXlm 6.1 versions are compatible). Sites that have existing license
servers running an older version must shut down the servers and restart
them using the lmgrd and modeltech or mgcld daemon provided in this
release. The 6.1g FLEXlm license server is compatible with pre-5.3
versions of ModelSim.
From an earlier version of EE
If you run ModelSim EE, and are upgrading to ModelSim SE 5.7, you’ll
need a viewer license in order to run the GUI. Contact Model Technology
Sales for more information.
