Slide 10 of 93
Notes:
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.
