Introduction to Hardware Description Languages (HDLs)
P.V.R. Raja, Dushyant Kumar Singh, Himani Jerath · 2020
Hardware description language (HDL) is a specialized programming language used to label the electronic and digital logic modules. The building process and also plan of the modules are made through HDL program. HDL enables the simulation output and building blocks of digital logic circuit by using textual representation of input, output, operation, and appearance. The compilation of HDL will convert textual format into gate level, and the same has been on the FPGA processor by using synthesis and implementation process. The language assists to define any digital circuit in the system of physical. There are three HDLs commonly used to define the behavior of the digital modules—Verilog, VHDL, and System-C. The VHDL and Verilog are the oldest languages as compare with System-C that is most and commonly used.
