Hi.

 

a) for signals, you should use methods 'read' and 'write' instead of assignment.

 

you are using sc_lv which is a vector of sc_logics together with sc_bit. Maybe, you should think about using sc_bv (vector of bits) instead of sc_lv or sc_logic instead of sc_bit.

 

c) ctrl_ac.write(ctrl.read()[0]);

thank you very much

By the way, sc_bit was deprecated in 1666-2005 (10 years ago!) so it's preferred to use bool,

you can also use -

ctrl_ac.write( ctrl.read().to_uint() & 0x01 );
