SystemC: instantiating VHDL UM-219
Following the example shown above (UM-218), let’s see the generic information that would
be passed to the SystemC foreign module declaration. The generic parameters passed to the
constructor are shown in magenta color:
class counter : public sc_foreign_module {
public:
sc_in clk;
...
counter(sc_midule_name nm, char* hdl_name
int num_generics, const char* generic_list)
: sc_foreign_module(nm, hdl_name, num_generics,
generic_list),
{}
};
The instantiation is:
Example of generic use
dut = new counter ("dut", "work.counter", 9, generic_list);
Here is another example, a ring buffer, complete with all files necessary for the simulation.
// ringbuf.h
#ifndef INCLUDED_RINGBUF
#define INCLUDED_RINGBUF
class ringbuf : public sc_foreign_module {
public:
sc_in clk;
...
counter(sc_midule_name nm, char* hdl_name
int num_generics, const char* generic_list)
: sc_foreign_module(nm, hdl_name, num_generics,
generic_list),
{}
};
#endif
---------------------------------------------------------------------------
// test_ringbuf.h
#ifndef INCLUDED_TEST_RINGBUF
#define INCLUDED_TEST_RINGBUF
#include "ringbuf.h"
SC_MODULE(test_ringbuf)
{
sc_signal iclock;
...
...
