Understanding logic chip architecture is essential for successful FPGA and CPLD development. Common building blocks feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which incorporate lookup tables and flip-flops, coupled with programmable interconnect lines. CPLDs generally employ sum-of-products structure arranged in logic array blocks, while FPGAs offer a more fine-grained structure with many smaller CLBs. Careful consideration of these fundamental aspects during the planning process contributes to reliable and effective solutions.
