The Proteus 8.13 Design Suite combines ease of use with a powerful feature set to enable the rapid design, test, and layout of professionally printed circuit boards. Ref data may be found in the Content Center. The microcontrollers 8051, ARM7, ARM Cortex-M3, AVR, Texas Instruments, Motorola, PIC, and Basic Stamp may all be simulated using Proteus Professional. The Proteus Professional package also comes with a PCB design program. The Proteus Professional package's capacity to mimic the functioning of programmable devices, such as microcontrollers, microprocessors, DSPs, etc., is one of its distinguishing features. The package is a system for simulating circuits that are based on the electronic component models used in PSpice. A software program for the computer-aided design of electrical circuits is called Proteus 8 Professional.
