The Hardware Description Language Lola

Lola was designed as a simple, easily learnable hardware description language for describing synchronous, digital circuits. In addition to its use in a digital design course for second year computer science students at ETH Zürich, the Institute for Computer Systems uses it as a hardware description language for describing hardware designs in general and coprocessor applications in particular.
The purpose of Lola is to statically describe the structure and functionality of hardware components and of the connections between them. A Lola text is composed of declarations and statements. It describes the hardware on the 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 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).
