VHDL

<p>VHDL (<a href="/facts/Very_High_Speed_Integrated_Circuit_Program/v9ARxl49">VHSIC</a> Hardware Description Language) is a <a href="/facts/Hardware_description_language/g19KvKCu">hardware description language</a> that can model the behavior and structure of <a href="/facts/Digital_electronics/3kJcKbkw">digital systems</a> at multiple levels of abstraction, ranging from the system level down to that of <a href="/facts/Logic_gates/RHLulvKI">logic gates</a>, for design entry, documentation, and verification purposes. The language was developed for the US military <a href="/facts/Very_High_Speed_Integrated_Circuit_Program/v9ARxl49">VHSIC</a> program in the 1980s, and has been standardized by the <a href="/facts/Institute_of_Electrical_and_Electronics_Engineers/UddC4pUW">Institute of Electrical and Electronics Engineers</a> (IEEE) as IEEE Std 1076; the latest version of which is IEEE Std 1076-2019. To model <a href="/facts/Analogue_electronics/Bnlnfwwv">analog</a> and <a href="/facts/Mixed-signal_integrated_circuit/cDkjcck8">mixed-signal</a> systems, an IEEE-standardized HDL based on VHDL called <a href="/facts/VHDL-AMS/IRRos9XK">VHDL-AMS</a> (officially IEEE 1076.1) has been developed.
