line coverage problem with gcov

line coverage problem with gcov

[Ciro Ceissler]

Hello,

I trying to do coverage using gcov and can't reach 100% for line
coverage, for example:

#####:  32: SC_MODULE(test) {
        -:   33:        sc_in<bool> clk;
        -:   34:        sc_in<bool> arst_n;
        -:   35:
        -:   36:        void func1 ();
        -:   37:        void func2 ();
        -:   38:
      18:  39:        SC_CTOR(test)  {
      18:  40:                SC_CTHREAD(func1, clk.pos())
      18:  41:                async_reset_signal_is(arst_n, false);
        -:   42:
      18:  43:                SC_CTHREAD(func2, clk.pos());
      18:  44:                async_reset_signal_is(arst_n, false);
        -:   45:
        -:   46:        } // end of SC_CTOR
        -:   47: }; // end of SC_MODULE

From other project, I have another behavior (just put a stub from
module), here above:

      18:  32: SC_MODULE(test2) {
        -:   33:        sc_in<bool> clk;
        -:   34:        sc_in<bool> arst_n;
        -:   35:
      18:   36:        void func1 ();
      18:   37:        void func2 ();
        -:   38:
      18:  39:        SC_CTOR(test2)  {
      18:  40:                SC_CTHREAD(func1, clk.pos())
      18:  41:                async_reset_signal_is(arst_n, false);
        -:   42:
      18:  43:                SC_CTHREAD(func2, clk.pos());
      18:  44:                async_reset_signal_is(arst_n, false);
        -:   45:
        -:   46:        } // end of SC_CTOR
        -:   47: }; // end of SC_MODULE

I don't understand why SC_MODULE wasn't covered from the first
example, but SC_CTOR was.

Can anyone tell me why this happen or could suggest another tool for coverage?

Thanks,
