Remote system upgrade with AS of Stratix II and EPCS16

Just use the EPCS64. I did a Stratix II EP2S130 design and we were able to fit 4 images (with compression of course).

However, I would caution you on one other thing. The remote update functionality using AS devices can be tricky. I strongly encourage you to try your scheme on an existing development board. People often have a very difficult time using the altremote_update megacore. The Stratix II design I mentioned worked fine. The altremote_update core did not work as documented but it met our needs.

In contrast, I currently have a Stratix II GX EP2S130 design where I'm trying to do the exact same thing. I have yet to successfully get remote update working on it.

Anyway, just try it out before you buy off on it.
