Lola (computing)
hardware description language
Lola is a hardware description language for describing synchronous, digital circuits. Niklaus Wirth developed the language to teach digital design on field-programmable gate arrays (FPGAs) to computer science students while a professor at ETH Zurich.
The purpose of Lola is to statically describe the structure and function of hardware components and of the connections between them. A Lola text is composed of declarations and statements. It describes digital electronics hardware on the logic gate level in the form of signal assignments. Signals are combined using operators and assigned to other signals. Signals and the respective assignments can be grouped together into data types. An instance of a type is a hardware component. Types can be composed of instances of other types, thereby supporting a hierarchical design style and they can be generic, e.g., parametrizable with the word width of a circuit.
All of the concepts mentioned above are demonstrated in the following example of a circuit for adding binary data.
This brief starts where responsible research should: with the source description of “Lola (computing)” as hardware description language. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as hardware description language. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 25, 2025. The linked authority identifier is Q6668799. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
