Modules can be instatiated in SystemC.
Like the yxz module can be instatited like

xyz  xyz_inst("xyz_1");
  xyx_inst.clock( -- signal to connect to--);
  xyz_inst.din1  (-- signal to connect to --);
  xyz_inst.din2  (-- signal to connect to --);
  xyz_inst.dout1(-- signal to connect to --);
  xyz_inst.dout2(-- signal to connect to --);

For SystemC equivalent of assign

first a simple verilog module with an assign

module abc(
 din1
,din2
,sel
,dout1);

input din1;
input din2;
output dout1;

assign  dout1 = sel ? din1 : din2;
endmodule

In SystemC

SC_MODULE(xyz)
{
sc_in<bool> din1;
sc_in<bool> din2;
sc_out<bool> dout1;
void func()
{
dout1 = sel ? din1 : din2;
};
SC_CTOR(xyz)
{
SC_METHOD(func);
sensitive << din1 << din2;
}
};
