Architectural Description
Virtex-E Array
The Virtex-E user-programmable gate array (see
comprises two major configurable elements: configurable
logic blocks (CLBs) and input/output blocks (IOBs).
•
•
CLBs interconnect through a general routing matrix (GRM).
The GRM comprises an array of routing switches located at
the intersections of horizontal and vertical routing channels.
Each CLB nests into a VersaBlock™ that also provides local
routing resources to connect the CLB to the GRM.
The VersaRing™ I/O interface provides additional routing
resources around the periphery of the device. This routing
improves I/O routability and facilitates pin locking.
The Virtex-E architecture also includes the following circuits
that connect to the GRM:

CLBs provide the functional elements for constructing
logic.
IOBs provide the interface between the package pins
and the CLBs.
Dedicated block memories of 4096 bits each
Clock DLLs for clock-distribution delay compensation
and clock domain control
3-State buffers (BUFTs) associated with each CLB that
drive dedicated segmentable horizontal routing resources

Virtex™-E 1.8 V Extended Memory
Field Programmable Gate Arrays
Production Product Specification
Values stored in static memory cells control the configurable
logic elements and interconnect resources. These values
load into the memory cells on power-up, and can reload if
necessary to change the function of the device.
Input/Output Block
The Virtex-E IOB,
outputs that support a wide variety of I/O signalling stan-
dards (see
The three IOB storage elements function either as
edge-triggered D-type flip-flops or as level-sensitive latches.
Each IOB has a clock signal (CLK) shared by the three
flip-flops and independent clock enable signals for each
flip-flop.
