Problem Title:
XACT 5 library guide: incorrect F3 carry logic connection in figure 4-18
Problem Description:
Solution 1:
Figure 4-18 on page 4-98 of the XACT 5 Libraries guide shows the F3
input to the block labeled "F Carry Logic" is sourced by the multiplexer
which selects between the F4 input to the CLB and the CIN input (just
below the middle left).
(The "inputs to the CLB" are on the far left side of the diagram.)
As the name suggests, however, the F3 input to the "F Carry Logic" block
should be sourced by the F3 input to the CLB.
