Where is declared SC_OFF?


Recommended Posts



After I define fixed point, the last line 





#define SC_INCLUDE_FX 
#include <systemc.h>
#include "fir_data.h"
void fir_data::entry()
  int state;
  sc_int<8> sample_tmp;
  sc_ufixed<16,16> d;        

is complained by compiler:


# fir_data.cpp:44: error: no match for call to '(sc_dt::sc_ufixed<16, 16, SC_TRN, SC_WRAP, 0>) (sc_dt::sc_switch)'
# C:\modeltech_10.1c\include\systemc/sc_fxnum.h:3372: note: candidates are: const sc_dt::sc_fxnum_subref sc_dt::sc_fxnum::operator()(int, int) const
# C:\modeltech_10.1c\include\systemc/sc_fxnum.h:3383: note:                 sc_dt::sc_fxnum_subref sc_dt::sc_fxnum::operator()(int, int)

What is wrong with my code?

SC_ON, SC_OFF are related to "floating-point cast switches". You likely don't need to worry about these, if you don't know what problems these intend to address.  Otherwise, please refer to Sections 7.10.7, 711.5 of IEEE 1666-2011.


Syntaxwise, you currently try to invoke the function call operator on the sc_ufixed variable d (with an incompatible parameter).
What do you intend to achieve?  Do you want to assign a value?
