Recursive sc_trace for all sc_signal channels


Recommended Posts


I wish to perform a trace for all the signals in my design.
Since I didn't find a reference how to do this, I tried to implement it by myself.
The main concept I used is to run recursively on all child objects of sc_module objects (using the get_child_objects() method).
If a child object is sc_signal, the sc_trace method is performed.

I created a test-case and ran it with Accellera compiler 2.3. However, I'm getting the following warning:

Warning: (W710) object cannot not be traced: system.sig
In file: ..\..\src\sysc\tracing\sc_trace.cpp:145

Could you please help me to fix the code?

Your trace function calls sc_trace(sc_trace_file *, sc_object*, const char*) which is not overloaded and hence issues the warning.

You would need to test for each single template instance of sc_signal<T> and then call the appropriate sc_trace function. And example you can find in https://git.minres.com/SystemC/SystemC-Components/src/branch/master/src/tracer_base.cpp#L90. Or you may use the SystemC Components Library (SCC) as a whole since it provides already this functionality.

Best regards
