Hi @Xuan,
The socket connection error you are encountering during HDL Cosimulation with Cadence Xcelium can stem from several factors. Please see my comments below.
xmsim.log is below.

********************************************************************** HDL server has been started in batch mode. The HDL simulator will be blocked until Simulink starts cosimulation. If you do not want to run in batch mode, restart the HDL simulator in a different run mode. To exit the HDL simulator without running a cosimulation session, issue the breakHdlSim('42755') command in MATLAB. Unexpected error from server thread: Shutting down xmsim: *E,IONOEN: file does not exist, exit. xcelium> exit xmsim: *W,NORUNCMD: No 'run' command issued.
Comment: The log indicates that the HDL server is running in batch mode. To resolve this, restart the HDL simulator in interactive mode. This can be done by modifying the simulation settings in your HDL simulator.
You mentioned, “Unfortunately, I get an error of socket connection.”
Comment: You have to make sure that there are no firewall settings or network configurations blocking the socket connection. Temporarily disabling the firewall can help identify if this is the issue. Also, verify that all paths to the necessary files and libraries are correctly set in your MATLAB environment. Missing files can lead to connection errors.
Your log file displayed message, “issue the breakHdlSim('42755') command in MATLAB.”
Comment: The log file is clearly giving you a clue that if you wish to exit the HDL simulator without running a cosimulation session, use the command breakHdlSim('42755') as suggested in the log.
Lastly, make sure that the versions of MATLAB, Simulink, and Cadence Xcelium are compatible with each other. Sometimes, version mismatches can lead to unexpected errors.

By following these suggestions, hopefully you should be able to resolve the socket connection issue and successfully run your HDL cosimulation.
