This book focuses on presenting the basic features of the VHDL language in the context of its use for both simulation and synthesis. Basic language concepts are motivated by familiarity with digital logic circuits with simulation and synthesis presented as complementary design processes. Field programmable gate arrays are used as the medium for synthesis laboratory exercises, and tutorials are provided for the use of the new integrated design environments from Xilinx--which is available with the book. For engineers interested in Digital Design Laboratory, Digital Design, Advanced Digital Design, and Advanced Digital Logic
