AUTO_PARALLEL_EXPANDERS
Allows the Compiler to automatically create chains of parallel expander product terms. Parallel expanders
are available in macrocells, that is, embedded cells within an Embedded System Block [ESB] that is set to
use Product Term mode. The length of the chains is controlled with the Parallel Expander Chain Length
option. The Auto Parallel Expanders option is ignored if you select 'LUT' or 'ROM' as the setting for the
Technology Mapper option.
