FLEX 10K Embedded Programmable Logic Family Data Sheet
Figure 12 shows the interconnection of adjacent LABs and EABs with row,
column, and local interconnects, as well as the associated cascade and
carry chains. Each LAB is labeled according to its location: a letter
represents the row and a number represents the column. For example,
LAB B3 is in row B, column 3.
