Understanding programmable component architecture is vital for effective FPGA and CPLD development. Typical building modules feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which house lookup registers and flip-flops, coupled with flexible interconnect lines. CPLDs generally use sum-of-products structure arranged in logic array blocks, while FPGAs provide a more detailed structure with many smaller CLBs. Detailed consideration of these fundamental aspects during your planning phase results to robust and efficient solutions.
