Description
The ModelSim-Altera Edition software requires a separate license for each simulation session. Due to an error in versions 10.0b and earlier, users may have been able to launch multiple simulation sessions with a single license. In version 10.1d and later, this error has been corrected. If you attempt to launch multiple simulation sessions, you may see the error below:
# ** Error: License checkout has been disallowed because
# only one session is allowed to run on an uncounted nodelock
# license and an instance of ModelSim is already running with a
# nodelocked license on this machine.
