Hardware description language (HDL) is a specialized computer language used to program electronic and digital logic circuits. The structure, operation, and design of the circuits are programmable using HDL. Instead of generating a computer-executable file, the HDL compilers provide a gate map. The gate map obtained is then downloaded to the programming device to check the operations of the desired circuit. The HDLs will allow fast design and better verification. The three commonly used HDLs are the following: Verilog HDL, VHDL (very high-speed integrated circuit hardware description language), and SystemC. Moore&s;s law in the year 1970 has brought a drastic change in the field of integrated circuit technology. This change has made developers bring out complex digital and electronic circuits. HDL simulation, which involves the need for a test bench. A test bench is an environment used to check the correctness of the design.
