Logic Modules
ACT 3 logic modules are enhanced versions of the 1200XL family logic modules. As in the 1200XL
family, there are two types of modules: C-modules and S-modules (Figure 2-2 and Figure 2-3). The C-
module is functionally equivalent to the 1200XL C-module and implements high fanin combinatorial
macros, such as 5-input AND, 5-input OR, and so on. It is available for use as the CM8 hard macro. The
S-module is designed to implement high-speed sequential functions within a single module.
S-modules consist of a full C-module driving a flip-flop, which allows an additional level of logic to be
implemented without additional propagation delay. It is available for use as the DFM8A/B and DLM8A/B
hard macros. C-modules and S-modules are arranged in pairs called module-pairs. Module-pairs are
arranged in alternating patterns and make up the bulk of the array. This arrangement allows the
placement software to support two-module macros of four types (CC, CS, SC, and SS). The C-module
implements the following function:
Y = !S1 * !S0 * D00 + !S1 * S0 * D01 + S1 * !S0 * D10 + S1 * S0 * D11
EQ 1
where: S0 = A0 * B0 and S1 = A1 + B1
