Understanding configurable device architecture is critical for successful FPGA and CPLD development. Standard building blocks include Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which incorporate lookup tables and flip-flops, coupled with reconfigurable interconnect lines. CPLDs generally employ sum-of-products structure positioned in programmable array blocks, while FPGAs offer a more fine-grained structure with many smaller CLBs. Thorough consideration of these fundamental aspects during the development phase leads to stable and effective designs.
