ofstream not working inside SC_CTHREAD

[Nithin]

Hi,

I am not able to do file write operations inside SC_CTHREAD. Is that expected? Is that a known behavior with SC_CTHREAD? It doesn't give any error, but the file is empty. The same file write operations work in an SC_THREAD though.

Here is my SC_CTHREAD function.

void MOD::READ_FROM_FIFO() {
  sc_bv<6> S_val;
  ofstream f1;
  f1.open ("output.txt");
  while(true) {
    S_val = FIFO.read();
    S.write(S_val);
    f1 << "READ_FROM_DS_FIFO DBG1: S_val= " << S_val<< "\n";
    wait();
  }
  f1.close();
}

Any guidance is appreciated. Thanks in advance.

Regards,

Nithin

Your problem is definitely not SystemC. You did not specify how it’s not working. I have some observations though:

1. f.close is not reachable due to the infiinite loop. 
2, you did not check for the success of opening the file.
