A Circuit Simulation of Micro-Processor Model: using DSCH Software

 The DSCH program is a logic editor and simulator designed by a research group under the leadership of E.Sicard, a professor of INSA of Toulouse . DSCH is used to validate the architecture of the logic circuit before the microelectronics design is started. DSCH provides a user-friendly environment for hierarchical logic design, and fast simulation with delay analysis, which allows the design and validation of complex logic structures. The basic version is available online at http://www.microwind.net. Abstract With popularizing computers and large-scale integrated circuits, designing of digital system has shifted from traditional manual model to circuit design using integrated circuit computer-aided design tools. That means hardware design is becoming software-oriented [1]. This paper designs a circuit of 4-bit digital micro-processor model by using logic simulation software DSCH, analyses functional mechanism of each module, and simulates its logic function.
