MACH 4 Family
Macrocell
The macrocell consists of a storage element, routing resources, a clock multiplexer, and
initialization control. The macrocell has two fundamental modes: synchronous and
asynchronous (Figure 5). The mode chosen only affects clocking and initialization in the
macrocell.
In either mode, a combinatorial path can be used. For combinatorial logic, the synchronous
mode will generally be used, since it provides more product terms in the allocator.
