FLEX 10K Embedded Programmable Logic Device Family Data Sheet
Logic Array Block
Each LAB consists of eight LEs, their associated carry and cascade chains,
LAB control signals, and the LAB local interconnect. The LAB provides
the coarse-grained structure to the FLEX 10K architecture, facilitating
efficient routing with optimum device utilization and high performance.
