Thank you for taking time to go through the code and pointing out the problem, also thank you for your valuable suggestions. I also had to explicitly convert the read value to bool before writing it to output. // Multiplexer Logic void mux(){ // Convert bit vector to int int select_value = s_i.read().to_uint(); sc_bv<4> in = i_i.read(); switch(select_value){ case 0 : y_o.write(in[0].to_bool()); break; case 1 : y_o.write(in[1].to_bool()); break; case 2 : y_o.write(in[2].to_bool()); break; case 3 : y_o.write(in[3].to_bool()); break; default : y_o.write(false); } } I have limited knowledge in filed of system level design, but how modules will be designed if SC_MODULE macro is discontinued.

Hi, I am new to system c and in the process of exploring I am facing below Issue please help me out in finding out the root cause.
