hello ,,

 

i wish to use string as input data type i have used ...

sc_in<unsigned char> data_in;

and i am using data_in as static sensitivity ....and am getting error :

ca_fifo.h: In constructor ‘fifo::fifo(sc_core::sc_module_name)’:
ca_fifo.h:27:6: error: invalid static_cast from type ‘void (fifo::*)(char)’ to type ‘sc_core::SC_ENTRY_FUNC {aka void (sc_core::sc_process_host::*)()}’

please explain me the above error as i wish to sent a string literal from stimulus ...

 

and on page 199 of 1666-2011 string literals topic ...it is written

"

A string literal representation may be used as the value of a SystemC numeric or vector type object."

 

does it mean that we cannot sent a string literal directly ...

 

thanks

#include <systemc.h>

SC_MODULE (fifo)
{
  sc_in<bool> read_write_n;
  sc_in<unsigned char> data_in;
  sc_in<bool> clock;
  sc_in<bool> reset;
  
  sc_out<bool> output;

  void fifo_read();
  void fifo_write(unsigned char c);
  void fifo_reset();

  sc_event write_event,read_event;
  enum e{MAX=10};
  char data[MAX];
  int num_element,first;

 SC_CTOR (fifo)
  {
     SC_THREAD(fifo_read);
     sensitive<<read_write_n;
     sensitive_pos<<clock;
      
     SC_THREAD(fifo_write);
     sensitive<<read_write_n;//<<data_in;
     sensitive<<data_in;
     sensitive_pos<<clock;

     SC_THREAD(fifo_reset);
     sensitive<<reset;
   }   
};

error is
