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.

We are not aware of such license checkout issue.
Please reach out to if you continue to face issues and for licensing help.

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.
