Configurable Logic Block (CLB) and
Slice Resources
For additional information, refer to the “Using Configurable
Logic Blocks (CLBs)” chapter in UG331.
CLB Overview
The Configurable Logic Blocks (CLBs) constitute the main
logic resource for implementing synchronous as well as
combinatorial circuits. Each CLB contains four slices, and
each slice contains two Look-Up Tables (LUTs) to imple-
ment logic and two dedicated storage elements that can be
used as flip-flops or latches. The LUTs can be used as a
Table 9: Spartan-3E CLB Resources
Slices
Each CLB comprises four interconnected slices, as shown
in
organized as a column with an independent carry chain.
The left pair supports both logic and memory functions and
its slices are called SLICEM. The right pair supports logic
only and its slices are called SLICEL. Therefore half the

The number of CLBs is less than the multiple of the rows and columns because the block RAM/multiplier blocks and the DCMs are
embedded in the array (see

16x1 memory (RAM16) or as a 16-bit shift register (SRL16),
and additional multiplexers and carry logic simplify wide
logic and arithmetic functions. Most general-purpose logic
in a design is automatically mapped to the slice resources in
the CLBs. Each CLB is identical, and the Spartan-3E family
CLB structure is identical to that for the Spartan-3 family.
CLB Array
The CLBs are arranged in a regular array of rows and col-
umns as shown in
Each density varies by the number of rows and columns of
CLBs (see
LUTs support both logic and memory (including both
RAM16 and SRL16 shift registers) while half support logic
only, and the two types alternate throughout the array col-
umns. The SLICEL reduces the size of the CLB and lowers
the cost of the device, and can also provide a performance
advantage over the SLICEM.
