VHDL, and output a definition of the physical implementation of the circuit. In addition to IEEE standard 1164, several child standards were introduced to extend functionality of the language. 2 added better handling of real and complex data types. While maintaining full compatibility with older versions, this proposed standard provides numerous extensions that make writing and managing VHDL code easier. These changes should improve quality of synthesizable VHDL code, make testbenches more flexible, and allow wider use of VHDL for system-level descriptions.
In February 2008, Accellera approved VHDL 4. 0 also informally known as VHDL 2008, which addressed more than 90 issues discovered during the trial period for version 3. 0 and includes enhanced generic types. In 2008, Accellera released VHDL 4. 0 to the IEEE for balloting for inclusion in IEEE 1076-2008. 1983 to a team with Intermetrics, Inc.

The design database becomes progressively more laden with technology, a program designed to implement the underlying semantics of the language statements and simulate the progress of time provides the hardware designer with the ability to model a piece of hardware before it is created physically.
The language has undergone numerous revisions and has a variety of sub-standards associated with it that augment or extend it in important ways. 1076 was and continues to be a milestone in the design of electronic systems. First standardized revision of ver 7. 2 of the language from the United States Air Force. Significant improvements resulting from several years of feedback. Probably the most widely used version with the greatest vendor tool support. Major revision released on 2009-01-26.
VHDL is commonly used to write text models that describe a logic circuit. Such a model is processed by a synthesis program, only if it is part of the logic design. A simulation program is used to test the logic design using simulation models to represent the logic circuits that interface to the design. This means that each transaction is added to an event queue for a specific scheduled time. The simulation alters between two modes: statement execution, where triggered statements are evaluated, and event processing, where events in the queue are processed.
