In addition to the four basic LCs, the Virtex-E CLB contains
logic that combines function generators to provide functions
of five or six inputs. Consequently, when estimating the
number of system gates provided by a given device, each
CLB counts as 4.5 LCs.
Look-Up Tables
Virtex-E function generators are implemented as 4-input
look-up tables (LUTs). In addition to operating as a function
generator, each LUT can provide a 16 x 1-bit synchronous
RAM. Furthermore, the two LUTs within a slice can be com-
