title: Automatic warning on fixed point overflow in SystemC
body: <p>Is there a way i can enable an automatic warning for my SystemC simulation whenever a fixed point variable overflows?</p>
  
  <p>I already discovered the overflow_flag() function, but that one have to be check manually for every time i write to a signal in my code. Also, as I interpret the documentation, this flag does not discern between overflowing and precision loss?</p>
