The document discusses different types of programmable logic devices including ASIC, FPGA, and CPLD. It describes the design flow for ASICs and lists common EDA tools for synthesis, simulation, and design entry. Key features of FPGAs are explained such as flexibility, density, cost effectiveness, and avoiding problems of ASICs. The internal structures of CPLDs and FPGAs including lookup tables, I/O blocks, and programmable interconnects are covered. Details are provided on Xilinx Spartan-3 series FPGAs and a comparison is made between FPGAs and CPLDs.
