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.
