1.4 The Routing of CXP Links to VFGs
What Figure 1-2 above does not show is how the CXP link in this case is routed to the
VFG (ie. PCI space and acquisition engine). As hinted at in Figure 1-1, the board has
quite a bit of flexibility in this area. Each VFG has its own acquisition and control circuit
which can be connected to any of the available CXP link. Figure 1-3 shows the all the
theoretical routing possibilities.
Figure 1-3 Cyton-CXP Routing Between CXP Links and VFG
Figure 1-3 may look confusing, but all of the routing details are handle automatically
by software, there is no need to worry about programming the routing tables manu-
ally in your software. However, it is helpful to understand the underlying structure of
the Cyton.
Note: In certain situations, a VFG may have no CXP links routed to it, as they may all be
used by other VFGs. In this case, the VFG with no links can not be used for acquisition.
