Preliminary Information
APEX 20K Programmable Logic Device Family Data Sheet
APEX 20KE devices provide two additional dedicated clock pins, for a
total of four dedicated clock pins. APEX 20K devices also include
ClockLock and ClockBoost clock management circuitry.
MegaLAB Structure
APEX 20K devices are constructed from a series of MegaLAB structures.
Each MegaLAB structure contains 16 logic array blocks (LABs), one ESB,
and a MegaLAB interconnect, which routes signals within the MegaLAB
structure. Signals are routed between MegaLAB structures and to I/O
pins via the FastTrack Interconnect. In addition, edge LABs can drive I/O
pins through the local interconnect. Figure 2 shows the MegaLAB
structure.
Figure 2. MegaLAB Structure
Logic Array Block
Each LAB consists of 10 LEs, the LEs’ associated carry and cascade chains,
LAB control signals, and the local interconnect. The local interconnect
transfers signals between LEs in the same or adjacent LABs, IOEs, or ESBs.
The Quartus Compiler places associated logic within an LAB or adjacent
LABs, allowing the use of a fast local interconnect for high performance.
Figure 3 shows the APEX 20K LAB.
APEX 20K devices use an interleaved LAB structure. This structure allows
each LE to drive two local interconnect areas. This feature minimizes use
of the MegaLAB and FastTrack interconnect, providing higher
performance and flexibility. Each LE can drive 29 other LEs through the
fast local interconnect.
