Model of microcontroller for education purpose

Timofeev A., Ushakov P.

Studia Informatica : systems and information technology

2013

Vol. 1-2(17)

73--80

It is emphasized that simulation modeling of compound electronic devices is one of the effective methods of education and training of electronics engineers, but the problem of wide time to waiting of results in simulation modeling of compound electronic devices come into being. Programming system Amethyst design compound models, for which the waiting time of results is in reasonable limits. The model of microcontroller PIC18F6720, which is used on lessons "Embedded systems", is described and results of experiments with the model are presented. Experiments with the model lead to the conclusion that the model can be used in the process of education and training of electronics engineers.

Algorithms for calculation of electrical circuit state

Timofeev A., Ushakov P.

Studia Informatica : systems and information technology

2011

Vol. 1-2(15)

5--14

Algorithms of calculation of a state of an electric circuit with passive components are described. Algorithms are intended for usage in system of simulation of the mixed electronic devices. Each component of a circuit is presented by program model of high complexity. In this article the resistor model is described. Electric voltages in circuit nodes are calculated by method of summation of volt-ampere characteristics. Component models control iterations at calculation of circuit nodes voltage. Results of calculation of voltage in R-2R ladder of the digital-to-analog converter are presented.
