HDL Cosimulation with Cadence Xcelium setup

When running the example of "GettingStartedWithSimulinkHDLCosimExample" with Cadence Xcelium , I get these following messages.

Executing nclaunch tclstart commands...

Could you please guide me how to set up cosimulation with Cadence Xcelium?

The error messages you are encountering suggest a few potential issues with your setup, particularly related to environment variables and paths.

Ensure that the environment variables are correctly set for both MATLAB and "Cadence Xcelium". Specifically, check the following:

1. LD_LIBRARY_PATH: This should include paths to the necessary libraries for both MATLAB and Cadence Xcelium.

2. PATH: This should include the paths to the executable binaries for both MATLAB and Cadence Xcelium.

You can check and set these environment variables in your shell configuration file (e.g., .bashrc, .bash_profile, or .zshrc).

Further, the error "No such file or directory" indicates that the 'simvision' executable might not be found. Verify that the path to 'simvision' is correct and that the file exists. If the file does not exist, you might need to re-install or correct the installation path.

You can refer the official documentation for both MATLAB and "Cadence Xcelium" for more detailed setup instructions:

I hope this answer will help resolve the errors you are facing.
