Slice Location Designations
The Xilinx development software designates the location of
a slice according to its X and Y coordinates, starting in the
bottom left corner, as shown in
lowed by a number identifies columns of slices, increment-
ing from the left side of the die to the right. The letter ’Y’
followed by a number identifies the position of each slice in
a pair as well as indicating the CLB row, incrementing from
the bottom of the die.
the lower left-hand corner of the die. The SLICEM always
has an even ’X’ number, and the SLICEL always has an odd
’X’ number.

Slice Overview
A slice includes two LUT function generators and two stor-
age elements, along with additional logic, as shown in
