Hello @ANKUR SAINI,
If you are on Linux/UNIX with the Accellera release of SystemC library with the GNU toolchain, you can use the following tutorials for reference:
Due to the co-operative multi-tasking implementation of the SystemC library available from Accellera as @Roman Popov has mentioned, much of the debugging tasks are easier since all threads synchronize with the main library thread.
Let me know if it helps.
