APEX20K_TECHNOLOGY_MAPPER
Specifies whether to target look-up table (LUT) or Product Term when implementing logic in the device.
The Technology Mapper option allows you to determine whether logic is implemented in LABs or ESBs.
Depending on the setting of this option, other logic options may be ignored. For example, because carry
and cascade chains can only be implemented in LUTs, the Auto Carry Chains and Auto Cascade Chains
options are ignored if the 'Product Term' setting is selected. Similarly, because parallel expanders can only
be implemented in product terms, the Auto Parallel Expander Chains option is ignored if the 'LUT'
setting is selected.
