VHDL’s History (Cont.)
In July 1983, a team of Intermetrics, IBM and Texas Instruments were awarded a contract to develop VHDL
In August 1985, the final version of the language under government contract was released: VHDL Version 7.2
In December 1987, VHDL became IEEE Standard 1076-1987 and in 1988 an ANSI standard
In September 1993, VHDL was restandardized to clarify and enhance the language
VHDL has been accepted as a Draft International Standard by the IEC
The contract for the first VHDL implementation was awarded to the team of Intermetrics, IBM, and Texas Instruments in July 1983. However, development of the language was not a closed process and was subjected to public review throughout the process (accounting for Versions 1 through 7.1). The final version of the language, developed under government contract, was released as VHDL Version 7.2.
In March 1986, IEEE proposed a new standard VHDL to extend and modify the language to fix identified problems. In December 1987, VHDL became IEEE Standard 1076-1987. VHDL was again modified in September 1993 to further refine the language. These refinements both clarified and enhanced the language. The major changes included much improved file handling and a more consistent syntax and resulted in VHDL Standard 1076-1993.
