FPGA & CPLD Components: A Designer's Guide

Wiki Article

Understanding configurable device architecture is essential for effective FPGA and CPLD development. Standard building elements comprise Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which incorporate lookup tables and registers, coupled with programmable interconnect routes. CPLDs usually employ sum-of-products structure arranged in configurable array blocks, while FPGAs provide a more fine-grained structure with many smaller CLBs. Detailed consideration of these fundamental aspects during your planning process leads to stable and efficient solutions.
