/*
Ulli Holtmann, Nov/10/00
I would like to convert between sc_int and sc_bv like in this example:
*/
#include "systemc.h"
int sc_main(int argc, char* arg[])
{
sc_int<10> a;
sc_bv<10> b;
sc_int<7> c;
a=10; cout << "a="<< a << "\n";
b=a; cout << "b="<< b << "\n";
c=b; cout << "c="<< c << "\n";
return 0;
}
/*
This doesn't work on with either SC5.0 or g++ for different reasons.
SC 5.0
------------------------------------
compile error at assignment "c=b" == sc_int<7> = sc_bv<10> :
"/view/ccss_ulli/vobs/abc/src/scenic/scenery/include/sc_lv.h", line 165: Error: The function "convert" must have a prototype.
"str.cc", line 12: Where: While instantiating "sc_bv_ns::sc_lv<7>::sc_lv(const sc_bv_ns::sc_bv_base&)".
"str.cc", line 12: Where: Instantiated from non-template code.
file sc_lv.h:
#if !defined(__SUNPRO_CC)
template<class Y> sc_lv(const sc_proxy<Y>& y)
{init(y.back_cast().length()); assign_(y);}
template<class T> sc_lv& operator=(const sc_proxy<T>& t)
{ sc_bv_ns::assign_(*this,t); return *this;}
#else
// at least some constructors
sc_lv(const sc_bv<W>& t){convert(t);verify_length();}
sc_lv(const sc_lv_base& y):sc_lv_base(y){verify_length();}
sc_lv(const sc_bv_base& t){convert(t);verify_length();}
#endif
Apparently, the "convert" function is undeclared.
With gcc
------------------------------------
compiles fine, but then Abort at assignment "b=a" == sc_bv<10> = sc_int<10> :
a=10
Abort (core dumped)
I am using SystemC 1.0.1 (stellar does not yet have a 1.0.1 release entry). on
a Solaris 5.5.1 host with SC5.0 or g++ 2.95.2
