We have a user who is trying to use Matlab (concurrent licenses all on maintenance) under Linux, with Simulink and Simulink_HDL_Coder. The user is able to successfully obtain all three licenses. But when they try to generate the HDL code, the tool gives an error, “Unable to check out a license for HDL Coder”. This is in spite of the fact that we can see the user has the license checked-out.

Please help us resolve this issue.

Thanks

Another user had the matlab_coder license checked out and stuck even though he exited Matlab. Generating HDL requires both matlab_coder and simulink_hdl_coder. I had to have our IT dept do a hard-restart of the Matlab license server, which fixed the problem.
