Active Interconnect Technology
Local and global Virtex-II routing resources are optimized
for speed and timing predictability, as well as to facilitate IP
cores implementation. Virtex-II Active Interconnect Technol-
ogy is a fully buffered programmable routing matrix. All rout-
ing resources are segmented to offer the advantages of a
hierarchical solution. Virtex-II logic features like CLBs,
IOBs, block RAM, multipliers, and DCMs are all connected
to an identical switch matrix for access to global routing
resources, as shown in Figure 48.
Each Virtex-II device can be represented as an array of
switch matrices with logic blocks attached, as illustrated in
Figure 49.
