Simulation stopped by the user

[kihtrak]

Hello there, 

While trying to run the executable, I get the following message:

 

Info: (I703) tracing timescale unit set: 1 ns (decoder.vcd)

At time0 s:: (select, enable) 00output is 0

 

Info: /OSCI/SystemC: Simulation stopped by user.

 

Please suggest me on how to solve this issue. 

 

Thanks in advance.

Hi Kihtrak,

 

this looks like you got some output out of simulation and then it has finished with a call to sc_stop(). There is nothing so solve aside from that stdout and stderr seems to mixed a bit.

Hello Gerth. 

 

Since am a beginner to SystemC, am facing some difficulty in understanding what really the issue is. Can you please explain in detail?

 

 

//File: decoder_top.cpp

 

#include "driver.h"

#include "monitor.h"

#include "2_by_4_decoder.h"

 

 

int sc_main(int argc, char* argv[])

{

sc_signal<bool>  t_enable; 

sc_signal<sc_uint<2> > t_select; 

sc_signal<sc_uint<4> > t_z; 

 

 

 

 

sc_trace_file *wf = sc_create_vcd_trace_file("decoder"); 

wf->set_time_unit(1, SC_NS); 

 

 

decoder2by4 dcdr("2by4decodr"); 

dcdr.enable(t_enable);

dcdr.select(t_select); 

dcdr.z(t_z); 

 

 

driver dr("Waveform"); 

dr.d_enable(t_enable); 

dr.d_select(t_select); 

 

monitor mo1 ("MonitorWaveforms"); 

mo1.m_select(t_select); 

mo1.m_enable(t_enable);

mo1.m_z(t_z); 

 

sc_trace(wf, t_select, "t_select"); 

sc_trace(wf, t_enable, "t_enable"); 

sc_trace(wf, t_z, "t_z"); 

 

sc_start(100, SC_NS);

 

//if(not sc_end_of_simulation_invoked()) {

//cout<< "ERROR: Simulation stopped "; 

sc_stop(); 

//}

 

 

sc_close_vcd_trace_file(wf);

 

 

return(0); 

}

 

 

Result:

 

 

Info: (I703) tracing timescale unit set: 1 ns (decoder.vcd)

At time0 s:: (select, enable) 00output is 0

 

Info: /OSCI/SystemC: Simulation stopped by user.

 

 

Thanks in advance.

Probably your driver isn't doing anything. Try putting some printing statements in the driver to debug it,
