Multiplexer Primitives
Carry Chain Primitive
Port Signals
X-Ref Target - Figure 5-35
Two primitives (MUXF7 and MUXF8) are available for access to the dedicated F7AMUX,
F7BMUX and F8MUX in each slice. Combined with LUTs, these multiplexer primitives are
also used to build larger width multiplexers (from 8:1 to 16:1). The
Multiplexers
Data In – I0, I1
The data input provides the data to be selected by the select signal (S).
Control In – S
The select input signal determines the data input signal to be connected to the output O.
Logic 0 selects the I0 input, while logic 1 selects the I1 input.
Data Out – O
The data output O provides the data value (one bit) selected by the control inputs.
The CARRY4 primitive represents the fast carry logic for a slice in the Virtex-5 architecture.
This primitive works in conjunction with LUTs in order to build adders and multipliers.
This primitive is generally inferred by synthesis tools from standard RTL code. The
synthesis tool can identify the arithmetic and/or logic functionality that best maps to this
