Virtex™ 2.5 V Field Programmable Gate Arrays
Each block SelectRAM cell, as illustrated in
fully synchronous dual-ported 4096-bit RAM with indepen-
dent control signals for each port. The data widths of the
two ports can be configured independently, providing
built-in bus-width conversion.

The Virtex block SelectRAM also includes dedicated routing
to provide an efficient interface with both CLBs and other
block SelectRAMs. Refer to XAPP130 for block SelectRAM
timing waveforms.
Programmable Routing Matrix
It is the longest delay path that limits the speed of any
worst-case design. Consequently, the Virtex routing archi-
tecture and its place-and-route software were defined in a
single optimization process. This joint optimization mini-
mizes long-path delays, and consequently, yields the best
system performance.
The joint optimization also reduces design compilation
times because the architecture is software-friendly. Design
cycles are correspondingly reduced due to shorter design
iteration times.

Internal CLB feedback paths that provide high-speed
connections to LUTs within the same CLB, chaining
them together with minimal routing delay
Direct paths that provide high-speed connections
between horizontally adjacent CLBs, eliminating the
delay of the GRM.
