5A. Combinatorial Logic Option 1
generates two functions of four
variables each. One variable, A, must be common to both func-
tions. The second and third variables can be any choice among
B, C, Qx, and Qy. The fourth variable can be either D or E.
5B. Combinatorial Logic Option 2
generates any function of five
variables: A, D, E, and two choices among B, C, Qx, Qy.
5C. Combinatorial Logic Option 3
allows variable E to select
between two functions of four variables: both have common
inputs, A and D, and any choice among B, C, Qx, and Qy for
the remaining two variables. Option 3 can then implement
some functions of six or seven variables.
Figure 5. Combinatorial Logic Diagram
Figure 6 shows a modulo 8 binary counter with parallel
enable. It uses one CLB of each type. The partial func-
tions of six or seven variables are implemented by
using the input variable (.e) to dynamically select
between two functions of four different variables. For
the two functions of four variables each, the indepen-
dent results (F and G) may be used as data inputs to
either flip-flop or logic block output. For the single func-
tion of five variables and merged functions of six or
seven variables, the F and G outputs are identical.
Symmetry of the F and G functions and the flip-flops
allows the interchange of CLB outputs to optimize
routing efficiencies of the networks interconnecting
the logic and IOBs.
