Hi, I have a set of signals defined as: sc_signal<sc_logic> bit0; sc_signal<sc_logic> bit1; sc_signal<sc_logic> bit2; I have another buses defined as sc_signal<sc_bv<3> > bus_input; sc_signal<sc_bv<3> > bus_output; I would like to do this operation: bus_output = bit(i) & bus_input where i = 0,1,2 For this, I am writing this code: bus_output = (bit2.read(), bit1.read(), bit0.read()) & bus_input.read(); But this does not work. Compile is fine but only the bus_output is correctly being written. other bits are not getting updated. Can you please let me know what is the issue? Thanks, Sachin
