Understanding programmable device architecture is essential for effective FPGA and CPLD implementation. Typical building blocks include Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which house lookup registers and flip-flops, coupled with programmable interconnect lines. CPLDs typically use sum-of-products structure positioned in programmable array blocks, while FPGAs feature a more fine-grained structure with many smaller CLBs. Detailed consideration of these core aspects during a development cycle leads to reliable and efficient designs.
