Usually you should use sc_vector instead of array. The problem with array is that names of signals and ports in array will be initialized to meaningless values (port_0 ... port_1 ).
If you still want to use arrays, then bind with a loop.
Here is example, both for array and sc_vector.
#include <systemc.h>
static const int N_PORTS = 4;
struct dut : sc_module {
sc_in<int> in_array[N_PORTS];
sc_vector<sc_in<int>> in_vector{"in_vector", N_PORTS};
SC_CTOR(dut) {}
};
struct test : sc_module {
dut d0{"d0"};
sc_signal<int> sig_array[N_PORTS];
sc_vector<sc_signal<int>> sig_vector{"sig_vector", N_PORTS};
SC_CTOR(test) {
for (size_t i = 0; i < N_PORTS; ++i) {
d0.in_array[i](sig_array[i]);
}
d0.in_vector(sig_vector);
}
};
