Modeling and the Simulator of Digital Circuits in Object-Oriented Programming

A designing of digital circuits is based on hardware description languages (HDLs). The dominating standard of HDLs is the VHDL, which basing on a digital circuit structure, a net-list, and an event-driven algorithm. In the publication is presented a description of the digital circuit built in an object-oriented programming. The base assumptions of a description are a digital circuit diagram and an event-driven algorithm. The descriptions are expressed in terms of the C#. A first part of the method based on a conception, which is widely published. A second part of the method is our conception of implementing an event-driven algorithm, using "a reformulating".
