Global
Signals
The programmable register also supports an asynchronous clear function.
Within the ESB, two asynchronous clears are generated from global
signals and the local interconnect. Each macrocell can either choose
between the two asynchronous clear signals or choose to not be cleared.
Either of the two clear signals can be inverted within the ESB.
shows the ESB control logic when implementing product-terms.
Parallel Expanders
Parallel expanders are unused product terms that can be allocated to a
neighboring macrocell to implement fast, complex logic functions.
Parallel expanders allow up to 32 product terms to feed the macrocell OR
logic directly, with two product terms provided by the macrocell and 30
parallel expanders provided by the neighboring macrocells in the ESB.
The Quartus II software Compiler can allocate up to 15 sets of up to two
parallel expanders per set to the macrocells automatically. Each set of two
parallel expanders incurs a small, incremental timing delay.
