Honored Contributor --- Quote Start --- direct instantiation is awesome --- Quote End --- Its good for quick-and-dirty checks of code, but it introduces a compilation-order dependence which can be annoying.

If however you have a component declaration either in the file where you use the component, or in a package that the code references, then the compiler will only look for mycomponent after it has processed all the VHDL files. So, its 'awesome', but not perfect :) Cheers, Dave
