gpsim has been designed for accuracy including the entire PIC - from the core to the I/O pins and including the functions of all internal peripherals. This makes it possible to create stimuli and tie them to the I/O pins and test the PIC the same way you would in the real world.^[2]

The software can run natively in Windows using gpsimWin32, a port to Windows created by Borut Ražem.
