Essential VHDL provides a simple, hands-on approach to writing VHDL for RTL synthesis. It follows a systematic, "how-to" style and instructs readers on practical VHDL design. Although targeted primarily at programmable logic designers, the techniques presented in this book make it equally useful for those interested in real-world HDL VHDL for RTL synthesis.
