Re: vhdl problem

you have to declare an input port in your entity to receive the handshaking signal from other entity. The signal will come from the out port of the first entity if the two entities are at the same hierarchical levels.

If the receiving entity is instantiated in a top level entity which has to generate the handshake signal then the handshaking signal can be declared as a signal in the top level entity and can be ported to the receiving entity input port.

I wonder if I could make it clear to you.
