APEX 20K Programmable Logic Device Family Data Sheet
Logic Element
The LE, the smallest unit of logic in the APEX 20K architecture, is compact
and provides efficient logic usage. Each LE contains a four-input LUT,
which is a function generator that can quickly implement any function of
four variables. In addition, each LE contains a programmable register and
carry and cascade chains. Each LE drives the local interconnect, MegaLAB
interconnect, and FastTrack Interconnect routing structures. See Figure 5.
Figure 5. APEX 20K Logic Element
Each LE’s programmable register can be configured for D, T, JK, or SR
operation. The register’s clock and clear control signals can be driven by
global signals, general-purpose I/O pins, or any internal logic. For
combinatorial functions, the register is bypassed and the output of the
LUT drives the outputs of the LE.
