Understanding configurable device architecture is critical for successful FPGA and CPLD implementation. Common building modules feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which incorporate lookup tables and flip-flops, coupled with flexible interconnect resources. CPLDs generally use sum-of-products structure organized in configurable array blocks, while FPGAs feature a more detailed structure with many smaller CLBs. Careful consideration of these core elements during a design phase leads to reliable and optimized implementations.
