So. What does style depend on?
@kaz, your advice good, add it to @Tricky and we get "make as many architecture you want, then make new entity where all desired architecture instained through configuration or direct instance. Enjoy". I 'll get one file with all desired architecture that wlll be a parallel structure .
Open any Viewer (RTL,Topology) and "enjoy" (sarcasm). Is it convenienced for me?
It 's better to add in quartus ability to choose which architecture(s) to open. I don't like the way that exist for today.
