there are several enhancements in VHDL 2008 to reduce verbosity; and I am just trying to find a thread, white paper, or link somewhere that explicity states the VHDL 2008 supported features in Quartus 10. What would be nice is a app note by Altera that maybe takes one of Jim Lewis Synth...

Once these components are defined they can be used as blocks, cells or macros in a higher level entity. This can significantly reduce the complexity of large designs. Hierarchical design approaches are always preferred over flat designs. We will illustrate the use of a hierarchical design approach...
you won't get those benefits immediately. Your first VHDL-based project will probably take slightly longer than if you had used your previous design process. Where you really win out is second time around. In order to reduce the time spent on your first project and to ensure that subsequent...
