Understanding programmable chip architecture is critical for optimized FPGA and CPLD design. Common building modules feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which contain lookup tables and registers, coupled with reconfigurable interconnect routes. CPLDs typically employ sum-of-products configuration organized in programmable array blocks, while FPGAs offer a more detailed structure with many smaller CLBs. Careful consideration of these fundamental components during the development cycle contributes to stable and optimized designs.
