Well,It is so pity that Quartus don't support some feature such as modports,modport expression, for they can provide a good way to hide some feature that we don't want module to access. It is very useful in developing between many developers.
But, in the limitation provided by the page,I still not found that the interface instantiated within interface is not supported:( . Have I missed anything?
