Understanding logic chip architecture is critical for successful FPGA and CPLD implementation. Standard building elements feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which contain lookup tables and latches, coupled with flexible interconnect resources. CPLDs usually employ sum-of-products structure positioned in logic array blocks, while FPGAs provide a more fine-grained structure with many smaller CLBs. Detailed consideration of these core elements during your design phase results to robust and efficient designs.
