Hi, Jonathan, Both the XAUI and the 10 GbE blocks provide high speed serial connectivity. The main difference is that the XAUI block provides a (less complex) point-to-point streaming interface with another XAUI block, whereas the 10 GbE block provides a (more complex) switchable (and I think even routable) datagram interface to any other 10 GbE enabled device. If you want to send high speed data from a casper device (e.g. roach) to a non-casper device (e.g. "receive computer"), the 10 GbE core is the only one that is suitable.
Hope this helps, Dave On Nov 30, 2010, at 2:56 PM, Jonathan Landon wrote: > When is it more appropriate to use the XAUI block instead of the ten_Gbe_v2 > block?
