Understanding configurable chip architecture is critical for effective FPGA and CPLD development. Common building elements comprise Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which contain lookup registers and registers, coupled with reconfigurable interconnect lines. CPLDs typically utilize sum-of-products configuration organized in logic array blocks, while FPGAs feature a more granular structure with many smaller CLBs. Detailed consideration of these basic elements during your development process contributes to stable and efficient solutions.
