Review of Digital Systems Design

In the first chapter, we presented an introduction to digital VLSI systems design and its applications, which is the main emphasis of this book. We pointed out how FPGA based systems offer better performance than processor based systems, yet remaining competitive. We also presented basic architectures and features of some of the latest FPGAs from a couple of leading vendors so that the reader may select the right type of FPGA for his or her design. Before we go into depths of Verilog based design of digital VLSI systems, we need to brush up our knowledge regarding the digital systems design using the conventional components such as gates, flip-flops, PALs, etc.
