1 ENTITY and several ARCHITECTURES

I have a question. If I have one entity and several architectures, which are relating to this entity how can I understand which architecture will be used?

It depends on the "configuration".

The VHDL "configuration" keyword allows you to select which architecture is used by which entity.

One other possibility is at instantiation, instead of just using the entity name, use entityname.architchecturename
