40MX and 42MX FPGAs
Figure 2 • 42MX C-Module Implementation
Figure 3 •
The 42MX devices contain three types of logic modules: combinatorial (C-modules),
sequential (S-modules) and decode (D-modules). The following figure illustrates the combinatorial logic
module. The S-module, shown in Figure 4, page 10, implements the same combinatorial logic function
as the C-module while adding a sequential element. The sequential element can be configured as either
a D-flip-flop or a transparent latch. The S-module register can be bypassed so that it implements purely
combinatorial logic.
