Creating a Virtual Copy of a Function Generator in the EVEEE Environment

With the development of the COVID-19 situation, the application of virtual laboratories became an indispensable part of engineering education. This study presents the design and implementation of a virtual function generator in the Engine for Virtual Electrical Engineering Equipment (EVEEE). The equipment is developed on two levels - functional and graphical. The functionality of the generator is implemented using a SPICE netlist containing several variables that are manipulated via the virtual components - several buttons and one potentiometer. On a graphical level, the generator is implemented using different PNG images, representing the equipment as a whole and its components individually. A virtual lab containing the function generator and a multimeter was created in order to test the developed functionality. The development of this virtual equipment extends the scope of application of the EVEEE environment, by allowing virtual investigation of classical circuit labs such as resonant circuits and filters.
