When to use asmi component?

Hello all, 

 

I have been told this asmi component is needed to get to some pins, for example spi pins on a cyclone. But I can't seem to find that information anywhere, does it depend on which pins are used in the PCB design, or are these pins from the device itself? I also can't seem to find such a datasheet that you know which pins are what, like if it has JTAG pins, where do I find these? 

 

But my main question here was: when do I use this ASMI component, when can't I assign the pins I need in my toplevel? 

 

I hope someone has any clue what I am talking about and can explain it to me. 

 

Thanks in advance, 

Greets,
