FPGA & CPLD Components: A Designer's Guide
Understanding programmable chip architecture is vital for successful FPGA and CPLD design. Typical building modules feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which house lookup tables and latches, coupled with programmable interconnect resources. CPLDs usually use sum-of-products structure positioned in configurable array blocks, while FPGAs feature a more detailed structure with many smaller CLBs. Thorough consideration of these core aspects during your design cycle leads to robust and efficient implementations.
