Understanding logic chip architecture is essential for optimized FPGA and CPLD implementation. Typical building elements feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which contain lookup registers and latches, coupled with reconfigurable interconnect lines. CPLDs usually employ sum-of-products configuration organized in configurable array blocks, while FPGAs provide a more fine-grained structure with many smaller CLBs. Detailed consideration of these fundamental aspects during a planning cycle results to stable and efficient designs.
