Özet: In recent years, Tablet PC type computers have reported a big boom, that we considered in the system design, which would enable to use their properties in the educational process. In this paper a novel approach to the design of logic circuit development system is presented, utilizing basic properties and advantages of the Tablet PC platform. It allows to develop the combinational or sequential logic circuit using library of common logic gates and flip-flops. These components may be selected not just from the corresponding library, but also by means of the panel for handwritten gestures recognition using stylus and touch-screen technology. The recognition may be customized creating the user-defined gestures that can then be recognized in addition to the default gestures already embedded in the system. Furthermore, the developed logic circuit can be simulated using an external simulator Icarus Verilog. The user can set logic values to the input buttons and the simulation results indicate the output LEDs. The program offers standard functions like storing and opening the designed circuit, exporting the schema into the PNG format as well as advanced function like displaying Verilog model of the designed circuit. Thanks to the easy and user friendly GUI the system has a potential to become a useful educational tool in courses devoted to digital circuits design.
