It is armed with the mixed-mode SPICE simulation. VSM (Virtual System Modelling feature allows the real time design simulation.
The user can design different electronic circuits with all the necessary components easily accessible from the simple yet effective interface like signal generators, power supply, simple resistor and a different microcontroller or microprocessor. Proteus provides a powerful working environment. This one aspect has attracted many users to select this tool amongst many others offering the same services. It has such a simple yet effective interface that it simplifies the task required to be performed. Proteus developed by Labcenter Electronics, is a software with which you can easily generate schematic captures, develop PCB and simulate microprocessor.
