Can anyone explain this error message

[lupineye]

I simulated a dural port memory with my top model.
then modelsim produced this error message!
I don't exactly understand what it means!
please make this message clear to me!

Thank you! so much!


Top level modules:
# glbl
# vsim -L xilinxcorelib_ver -L unisims_ver -lib work -t 1ps testbench1_vhd glbl
# ** Error: License checkout has been disallowed because

hello


ur using ip core does the modelsim library includes xilinxcore lib

Very likely that you have a Modelsim already running, hence the license failure. If you are on Linux, do:

  ps -ef | grep vsim

Even on Windows, under Cygwin you could do that or try the Task manager to find the old process.

Once you locate the old one, kill it, then launch your process again
