Designing Hardware With Software: Hardware Description Languages

Here's an idea: Use your software development skills to learn how to define a digital circuit in a hardware description language. You can program your design into a field-programmable gate array, resulting in a fully functional, high-performance custom digital device. Low-cost FPGA prototyping boards contain sufficient logic elements to implement complex modern processor designs such as RISC-V, along with any customized extensions you dream up.

Hardware description languages are not the exclusive province of digital designers at semiconductor companies; even hobbyists can make full use of these powerful, free tools. This article introduces the VHDL language, used widely in the development of FPGA circuit designs.
