Multiplexers
Virtex-II Pro function generators and associated multiplex-
ers can implement the following:

Fast Lookahead Carry Logic
Dedicated carry logic provides fast arithmetic addition and
subtraction. The Virtex-II Pro CLB has two separate carry
chains, as shown in the
The height of the carry chains is two bits per slice. The carry
chain in the Virtex-II Pro device is running upward. The ded-
icated carry path and carry multiplexer (MUXCY) can also

Each Virtex-II Pro slice has one MUXF5 multiplexer and
one MUXFX multiplexer. The MUXFX multiplexer imple-
ments the MUXF6, MUXF7, or MUXF8, as shown in

ples of multiplexers are shown in the Virtex-II Pro Platform
FPGA User Guide. Any LUT can implement a 2:1 multi-
plexer.
be used to cascade function generators for implementing
wide logic functions.
Arithmetic Logic
The arithmetic logic includes an XOR gate that allows a
2-bit full adder to be implemented within a slice. In addition,
a dedicated AND (MULT_AND) gate (shown in
improves the efficiency of multiplier implementation.
CLB

the two MUXF7 outputs
(Two CLBs)
MUXF6 combines the two MUXF5
outputs from slices S2 and S3
MUXF7 combines the two MUXF6
outputs from slices S0 and S2
MUXF6 combines the two MUXF6
outputs from slices S0 and S1
