Proteus 7.7 Professional with modified libraries

Proteus is a Virtual System Modelling and circuit simulation application. The suite combines mixed mode SPICE circuit simulation, animated components, and microprocessor models to facilitate co-simulation of complete microcontroller based designs. Proteus also has the ability to simulate the interaction between software running on a microcontroller and any analog or digital electronics connected to it. It simulates Input / Output ports, interrupts, timers, USARTs and all other peripherals present on each supported processor.

* Just download the torrent file in which you will find a folder. Navigate into that and then go to Bin Folder and run the ISIS.exe file to start the program.
You don't need to install the software.
