Module that convert an sc_vector input into sc_signal

[NicoCaldo]

I was wondering if it's possible to create a module that given as input an sc_vector<sc_in<bool> > containing a known number of sc_in<bool> (let's say 2) it would convert into a sc_out<sc_uint<2> >

Sure. Just add a method reading all bool sc_in and write to the output. You need to make it sensitive to all inputs Something like:

SC_MODULE(conv){
    sc_vector<sc_in<bool> > input{"input"};
    sc_out<bool> ouput{"ouput"};

    SC_CTOR(conv){
        SC_HAS_PROCESS(conv);
        SC_METHOD(method);
        for(auto& in: input){
            sensitive<<in;
        }
    }

    void method(){
        unsigned res = input[1]?2:0+input[0]?1:0;
        output=res;
    }
};

Thanks a lot but, your code use a bool as output.

I need to put together all the bool line in input as one line in output.

For istance if I have a vector of 2 bool input I want to took the two bit (i.e. a and b) and convert into a sc_uint<2> in out a*2^1+b*2^0

with 3 input, a,b, and c it would be a sc_uint<3> with a*2^2+b*2^1+c*2^0 and so on

That is a typo as the method() function shows. it Should read sc_out<sc_uint<2> >
