Is there any special way to start a clock - SystemC 2.3, 2.2?

Recommended Posts

Could some SystemC guru please help ?

I have in the test harness for a simple master slave

JK flip-flop the following clock:

sc_core::sc_clock clk("clk", 2.0, sc_core::SC_PS, 0.5);

.........

sc_core::sc_start(10.0, sc_core::SC_PS);

sc_core::sc_stop();

return 0;

}

However, the output always looks like:

0 jkmsff_0.inv_0 1 0

0 jkmsff_0.nnd3_0 0 1 0

0 jkmsff_0.nnd3_1 0 1 0

0 jkmsff_0.nnd3_1 1 1 0

0 jkmsff_0.nnd2_o2_0 1 0

0 jkmsff_0.nnd2_o2_1 1 0

0 jkmsff_0.nnd2_0 1 0

......

.....

Where the first 0 is supposed to be a time stamp

extracted as in an inverter

SC_MODULE(inv)

{

sc_core::sc_in<bool> din;

sc_core::sc_out<bool> dout;

bool b0;

void inv_proc0()

{

while(1)

{

wait();

b0 = din.read();

dout.write(!b0);

std::cout<<sc_core::sc_time_stamp().to_seconds()<<" "<<name()<<" "<<b0<<" "<<!b0<<std::endl;

}

}

SC_CTOR(inv):b0(false)

{

SC_THREAD(inv_proc0);

sensitive << din;

}

~inv(){}

};

The results are identical as SystemC 2.3.0, 2.2.0

Is there any glaring error ? I have used similar clocks

over and over in other modules, and they work just fine.

Any hints, suggestions would be of immense help.
