Understanding programmable device architecture is essential for successful FPGA and CPLD design. Typical building elements feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which house lookup arrays and latches, coupled with reconfigurable interconnect lines. CPLDs usually use sum-of-products structure positioned in logic array blocks, while FPGAs feature a more fine-grained structure with many smaller CLBs. Careful consideration of these fundamental components during the design process results to robust and optimized solutions.
