Hi Guys

Is it possible to connect sc_in<bool> hierarchically to another sc_in<bool> (same for sc_out<bool> as well) ?

I tried the attached exmples

ex1.cpp  Error: (E109) complete binding failed: port not bound: port 'target.target_h.in' (sc_in)

ex2.cpp : Error: (E109) complete binding failed: 2 binds exceeds maximum of 1 allowed: port 'target.in_h' (sc_in)
 

Can you please help me ?

Thanks

Khushi

Yes, but direction of binds matters. 

For example if you want to bind  ( in0 -> in1 -> signal  ) then you will need to write:

in0 ( in1 );
in1 ( signal );

OR

in1 ( signal );
in0 ( in1 );

In your examples you bind like this:

Ex1:  port0 <- port1 -> signal  // port0 not binded

Ex2:  signal <- port0 -> signal  // port0 binded to 2 signals 

I agree that error message in first case is misleading.
