Introduction To HDL Experiments: From Logic Gates to FPGAs: A Hands-On Guide to Hardware Description

In electronics, a hardware description language or HDL is any language from a class of Computer languages for formal description of electronic circuits. It can describe the circuit's operation, its design and organization, and tests to verify its operation by means of simulationHDLs are standard text-based expressions of the spatial, temporal structure and behavior of electronic systems. In contrast to a software programming language, HDL syntax, semantics include explicit notations for expressing time and concurrency, which are the attributes of hardware. Languages whose only characteristic is to express circuit connectivity between a hierarchies of blocks are properly classified as netlist languages.
