The use of Computer Hardware Description Languages plays an important role in the design automation process of digital systems. These languages help hardware engineers to provide a precise description of the internal structure of a system, and one of the most significant uses of these languages is as a means of input to a system simulator. AHPL is a hardware description language that describes a digital system as a set of modules and units. This language is supported by a function-level simulator (HPSIM2), but the simulator only provides support to the module descriptions of a system. This paper presents an improved version of the simulator that supports the use of unit descriptions called Combinational Logic Units or CLUNITs. The syntax and structure of a CLUNIT is analyzed, the operation and data structure of the simulator is given; and several examples are given to support these discussions.
