• VHDL is the VHSIC Hardware Description Language. VHSIC is an abbreviation for Very High Speed Integrated Circuit.

• It is a hardware description language that can be used to model a digital system.

• VHDL Can describe

  • behavior

  • structure

  • timing

  of a logic circuit.

• It is used to model the physical hardware used in digital systems.

• VHDL is commonly used to write text models that describe a logic circuit.

• VHDL allows designs to be described using any methodology - top down, bottom up or middle out.

• VHDL allows the behavior of complex electronic circuits to be captured into a design system for automatic circuit synthesis and system simulation.

• Features of VHDL:

  • It supports both synchronous and asynchronous timing models.

  • It is used as communication medium between CAD and CAE tools.

  • It supports flexible design methodologies.
