Introduction to Digital Design with VHDL

What is VHDL in digital design?
Very High-Speed Integrated Circuit Hardware Description Language (VHDL) is a description language used to describe hardware.
It is utilized in electronic design automation to express mixed-signal and digital systems, such as ICs (integrated circuits) and FPGA (field-programmable gate arrays).
What is the introduction of VHDL?
VHDL is used for documentation, verification and synthesis of large digital design. behavioral (generally a mixture of the three methods is used).
Every VHDL design description consists of at least one entity / architecture pair, or one entity with multiple architectures.
Why do we need VHDL?
The key advantage of VHDL, when used for systems design, is that it allows the behavior of the required system to be described (modeled) and verified (simulated) before synthesis tools translate the design into real hardware (gates and wires).
Another benefit is that VHDL allows the description of a concurrent system.
Basic concept to programming can be summarized as follow: Three main units constitute a VHDL code: a working library, an entity that describes the external view of the system and an architecture that describes the behaviour or internal structure of the system.
