Using the HET IDE and following the User's Guide v1.0 "Running a demo", the Assemble and Load step produces the following output in the IDE:
Info: (I804) /IEEE_Std_1666/deprecated: deprecated function: sc_get_default_time_unit
Warning: Unable to load document het.vcd
WARNING: Default time step is used for VCD tracing.
What is the interpretation of the above (deprecated function, unable to load het.vcd, warning on defulat time step)?
If this is a standard response, then it would be good to add this to the User's Guide with a user note.
