The use of VHDL

VHDL (VHSIC Hardware Description Language) is becoming increasingly popular as a way to capture complex digital electronic circuits for both simulation and synthesis. Digital circuits captured using VHDL can be easily simulated, are more likely to be synthesizable into multiple target technologies, and can be archived for later modification and reuse. — The correct and consistent design of computer hardware in a safety-critical system is extremely important. This feature necessitates a profound verification process related to the logic design of such a hardware. So far much work has been done on various verification methods, both formal and informal. verification method relies on automatic test-pattern generation (ATPG), where the VHDL model of the actual digital circuit is taken into consideration. VHDL is a programming language that has been designed and optimized for describing the behavior of digital circuits and systems. As such, VHDL combines features of the following:

A Simulation Modeling Language

A Simulation Modeling Language

A Test Language

A Netlist Language

A Standard Language

VHDL is a general-purpose programming language optimized for electronic circuit design. As such, there are many points in the overall design process at which VHDL can help

For design specification

For design capture

For design simulation

For design documentation

As an alternative to schematics

As an alternative to proprietary languages.
